High [CVE-2026-15554] Authentication Bypass via AJP ssl_cert/is_ssl Forgery
the Undertow AJP listener honours forged ssl_cert and is_ssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP protocol. Red Hat severity: Important — CVSS 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-295. Affected Red Hat products: Red Hat JBoss Enterprise Application Platform 7.4.25; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 8; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 9; Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 10; Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 8; Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 9; Red Hat JBoss Enterprise Application Platform 7. Red Hat lists Red Hat JBoss Enterprise Application Platform Expansion Pack as not affected. Red Hat fixing advisory: RHSA-2026:53806, RHSA-2026:53644, RHSA-2026:53645, RHSA-2026:53646, RHSA-2026:70230, RHSA-2026:70228, RHSA-2026:70229.
High [CVE-2026-72693] Local privilege escalation in openvt via incorrect process owner verification allowing passwordless root login
`openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat("/proc//fd/0")`. `stat()` on `/proc//fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path. A flaw was found in openvt (part of the kbd package) where incorrect process owner verification can allow a local unprivileged attacker to achieve passwordless root login.
High [CVE-2026-72694] MRTG daemon symlink-following chown allows local privilege escalation via PID file path manipulation
A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files. Red Hat severity: Important — CVSS 7.1 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-59. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat fixing advisory: RHSA-2026:57596, RHSA-2026:65832, RHSA-2026:57600. Affected products named by the advisory: Red Hat package: mrtg.
High [CVE-2026-4757] Code execution and privilege escalation via VAPIX API improper input validation
A VAPIX API parameter had improper input validation which could allow code execution and potentially lead to a privilege escalation. This flaw can only be exploited after authenticating with an administrator-privileged service account. A flaw was found in Axis. An attacker with an administrator-privileged service account could exploit improper input validation in a VAPIX API parameter. This could allow for arbitrary code execution and potentially lead to privilege escalation, granting the attacker higher system privileges. Red Hat severity: Important — CVSS 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-94. Affected Red Hat products: Red Hat Enterprise Linux 6. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: axis.
High [CVE-2026-66797] Velero Restore includes cluster-scoped RBAC resources with no exclusion — tampered backup yields hub cluster-admin
Improper access control in CloudStack's annotation functionality allows unauthorized comment creation and disclosure. The addAnnotation and listAnnotation APIs perform an ownership check when an entity's UUID is specified, but fail to honor its result correctly. This lets any authenticated user write annotations to, and disclose existing annotations/comments on, an entity they don't own by simply supplying its UUID. This issue affects Apache CloudStack: from 4.15.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue. A flaw was found in the cluster-backup-operator. An attacker with write access to the backup storage location or the ability to create a Velero Backup object can inject malicious Role-Based Access Control (RBAC) resources into a backup. This allows the attacker to gain administrative control over the entire cluster. This vulnerability is rated as an Important severity for Red Hat Advanced Cluster Management for Kubernetes because exploiting it requires high prerequisites, such as preexisting write access to external object storage or permissions to generate arbitrary backup definitions, despite resulting in full cluster takeover. Weakness: CWE-862.
High [CVE-2026-66798] Restore.spec.hooks passed verbatim to Velero Restore — arbitrary command execution in restored pods
Use after free in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network. A flaw was found in cluster-backup-operator. A namespace administrator in open-cluster-management-backup can create a Restore Custom Resource (CR) with malicious hooks. These hooks allow the execution of arbitrary commands within any matching restored pod, leading to the exfiltration of ServiceAccount tokens. This bypasses normal access controls, granting the attacker unauthorized execution access to pods and their associated Service Accounts. This vulnerability is rated as Important because an authenticated user with administrative access to the backup namespace can achieve cluster-wide privilege escalation. By defining custom restore operations containing uninspected execution hooks, an attacker circumvents standard pod execution controls across target restored workloads. This bypass enables unauthorized command execution and credential exfiltration across different namespaces, exceeding the boundary of the backup operator namespace. Red Hat severity: Important — CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-77.
High [CVE-2026-66799] Restore.spec.namespaceMapping pass-through enables cross-namespace Secret/ConfigMap placement
Heap-based buffer overflow in Windows Key Guard allows an authorized attacker to elevate privileges locally. A flaw was found in the cluster-backup-operator. A privileged user with administrative access to a specific namespace could exploit a vulnerability in the backup restoration process. This flaw allows them to redirect sensitive information, such as cloud provider credentials and access tokens, from backup operations into other namespaces, including those they control. This could lead to unauthorized access to critical system resources and the disclosure of confidential data. This is an Important vulnerability in Red Hat Advanced Cluster Management for Kubernetes. This allows for a cross-namespace write of credential material, potentially leading to unauthorized access to cloud provider credentials, pull secrets, and ManagedServiceAccount tokens. Red Hat severity: Important — CVSS 7.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N). Weakness: CWE-863. Red Hat fixing advisory: RHSA-2026:60390, RHSA-2026:60388, RHSA-2026:60389, RHSA-2026:57191, RHSA-2026:60386. Affected products named by the advisory: Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; Red Hat Advanced Cluster Management for Kubernetes 2.15; Red Hat Advanced Cluster Management for Kubernetes 2.16; and 1 more.
High [CVE-2026-66800] CleanupAll triggers unguarded cluster-wide mass-delete via operator ServiceAccount
Server-side request forgery (ssrf) in Azure Data Factory allows an unauthorized attacker to disclose information over a network. A flaw was found in cluster-backup-operator. A namespace administrator with privileges in the open-cluster-management-backup namespace can exploit a feature in the Restore Custom Resource (CR). By setting the cleanupBeforeRestore field to CleanupAll, an attacker can trigger an unguarded, cluster-wide deletion of all Red Hat Advanced Cluster Management (ACM) and Hive-labelled Secrets and ConfigMaps. This leads to a denial of service across the entire hub cluster by removing critical resources. This vulnerability is rated as Important. A namespace administrator within the `open-cluster-management-backup` namespace in Red Hat Advanced Cluster Management for Kubernetes can initiate a cluster-wide denial of service. Red Hat severity: Important — CVSS 7.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H). Weakness: CWE-862. Red Hat fixing advisory: RHSA-2026:60387, RHSA-2026:60390, RHSA-2026:60388, RHSA-2026:60389, RHSA-2026:60391, RHSA-2026:60386. Affected products named by the advisory: Red Hat Advanced Cluster Management for Kubernetes 2.11; Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; Red Hat Advanced Cluster Management for Kubernetes 2.15; and 2 more.

Affected products named by the advisory: Red Hat package: dotnet8.0; Red Hat package: dotnet9.0; Red Hat package: dotnet10.0.
High [CVE-2026-73266] tenant-controlled ClusterClaim labels propagated to ManagedCluster enabling cross-tenant ManagedClusterSet join
A flaw was found in the clusterclaims-controller component of Multicluster Engine (MCE). An authenticated tenant can exploit this vulnerability by manipulating ClusterClaim labels. This allows the tenant to force a cluster to join a ManagedClusterSet belonging to another tenant. Such unauthorized access could enable the injection of policies and workloads into other tenants' clusters. This Important flaw in Multicluster Engine for Kubernetes' clusterclaims-controller allows a tenant to propagate arbitrary labels from a ClusterClaim to a ManagedCluster object. This enables unauthorized cross-tenant ManagedClusterSet joins, leading to policy and workload injection into victim clusters. The vulnerability breaks tenant isolation, granting an attacker control over resources belonging to other tenants. Red Hat severity: Important — CVSS 7.1 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N). Weakness: CWE-441. Affected Red Hat products: multicluster engine for Kubernetes 2.10; multicluster engine for Kubernetes 2.11; multicluster engine for Kubernetes 2.17; multicluster engine for Kubernetes 2.6; multicluster engine for Kubernetes 2.8; multicluster engine for Kubernetes 2.9. Red Hat fixing advisory: RHSA-2026:59557, RHSA-2026:59556, RHSA-2026:59593, RHSA-2026:59579, RHSA-2026:59558, RHSA-2026:59559.
High [CVE-2026-73267] ManagedCluster deletion keyed solely on ClusterClaim.Spec.Namespace with no ownership check
A flaw was found in the clusterclaims-controller component of multicluster engine (MCE). A tenant with standard permissions to create and delete ClusterClaim resources can exploit this by manipulating the `spec.namespace` field. This allows the tenant to specify and delete any ManagedCluster, including the hub's local-cluster or other tenants' clusters, due to a missing ownership check. This vulnerability can lead to a denial of service by enabling unauthorized deletion of ManagedClusters. This is an Important flaw in Multicluster Engine for Kubernetes. Red Hat severity: Important — CVSS 7.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H). Weakness: CWE-602. Affected Red Hat products: multicluster engine for Kubernetes 2.1; multicluster engine for Kubernetes 2.11; multicluster engine for Kubernetes 2.17; multicluster engine for Kubernetes 2.6; multicluster engine for Kubernetes 2.8; multicluster engine for Kubernetes 2.9. Red Hat fixing advisory: RHSA-2026:59557, RHSA-2026:59556, RHSA-2026:59593, RHSA-2026:59579, RHSA-2026:59558, RHSA-2026:59559.
Medium [CVE-2026-18710] Credential disclosure via cleartext logging during client initialization
A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only. A flaw was found in org.mongodb/mongodb-driver. This allows them to reuse the credentials to authenticate to the associated network infrastructure, leading to information disclosure. This vulnerability has Moderate impact. A flaw in MongoDB driver components used by Red Hat products can lead to sensitive credential disclosure. An attacker with local access to these logs could recover and reuse the credentials, compromising confidentiality. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N). Weakness: CWE-312. Affected Red Hat products: Red Hat Build of Apache Camel 3.33.3.SP1; Red Hat Build of Debezium 3.6; Red Hat build of Quarkus 3.27.5.SP1; Red Hat build of Quarkus 3.33.3.SP1; Red Hat build of Apache Camel 4 for Quarkus 3.
Medium [CVE-2026-73242] Out-of-bounds memory access in Kerberos decryption
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP's winpr/libwinpr/sspi/Kerberos/kerberos.c kerberos_DecryptMessage function fails to bound the peer-controlled GSS Wrap-token EC field before using it with RRC in IOV pointer offsets, allowing a malicious RDP peer to trigger out-of-bounds reads and in-place writes during CredSSP/NLA Kerberos decryption. This issue is fixed in version 3.30.0. This occurs during CredSSP/NLA decryption and can lead to a denial of service or information disclosure. An Important out-of-bounds memory vulnerability in FreeRDP's CredSSP/NLA Kerberos decryption allows a malicious RDP endpoint to execute arbitrary code or expose sensitive information on connected clients and servers. This flaw only affects FreeRDP 3.0.0 and newer, meaning RHEL 9 and older versions are not affected. Red Hat severity: Moderate — CVSS 6.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:H). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat lists Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected. Red Hat fixing advisory: RHSA-2026:61378, RHSA-2026:68706. Affected products named by the advisory: Red Hat package: freerdp.
Medium [CVE-2026-71468] Cross-user bearer-token reuse via global federation-config cache
A flaw was found in acm-search-v2-api-rhel9. When the `getFederationConfig` function refreshes its cache, it improperly reuses a user's bearer token for all subsequent federated requests until the cache expires. This allows other authenticated users to gain unauthorized access to remote managed hub search results, leading to information disclosure. This Moderate impact flaw in Red Hat Advanced Cluster Management for Kubernetes allows for cross-user data access to remote managed hub search results. The vulnerability arises from the reuse of a bearer token across different user requests due to a shared cache. Exploitation requires the `FEATURE_FEDERATED_SEARCH` to be enabled, which is off by default and typically only configured in Global Hub deployments. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-266. Red Hat fixing advisory: RHSA-2026:60387, RHSA-2026:60390, RHSA-2026:60388, RHSA-2026:60389, RHSA-2026:60391, RHSA-2026:60386. Affected products named by the advisory: Red Hat Advanced Cluster Management for Kubernetes 2.11; Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; Red Hat Advanced Cluster Management for Kubernetes 2.15; and 2 more.
Medium [CVE-2026-71475] Spoke-controlled ClusterID injected unencoded into Insights API URL path
A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access. This vulnerability is rated as Moderate impact because exploiting it requires an attacker to already possess high privileges or full control over an enrolled managed spoke cluster. Because manipulating the cluster identifier requires administrative tampering with spoke-side status claims, external unauthenticated actors cannot leverage this flaw directly against the hub or the Insights service. Red Hat severity: Moderate — CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N). Weakness: CWE-22. Affected Red Hat products: Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; Red Hat Advanced Cluster Management for Kubernetes 2.15; Red Hat Advanced Cluster Management for Kubernetes 2.16; Red Hat Advanced Cluster Management for Kubernetes 2.17.
Medium [CVE-2026-71845] CCX_TOKEN bearer credential logged in clear text at startup via setDefault
A flaw was found in insights-client. The setDefault() function logs the value of every environment variable it processes, including CCX_TOKEN, a bearer credential used in disconnected cluster deployments. When glog verbosity is set to level 2 or higher, the token is written in clear text to the pod log on every startup. An attacker with access to pod logs or centralized logging could obtain the credential, leading to unauthorized access to the CCX API. This is a Moderate flaw in Red Hat Advanced Cluster Management for Kubernetes. This credential is used by disconnected cluster deployments as an alternative to cloud.redhat.com. Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N). Weakness: CWE-532. Red Hat fixing advisory: RHSA-2026:60387, RHSA-2026:60390, RHSA-2026:60388, RHSA-2026:60389, RHSA-2026:60391, RHSA-2026:60386. Affected products named by the advisory: Red Hat Advanced Cluster Management for Kubernetes 2.11; Red Hat Advanced Cluster Management for Kubernetes 2.13; Red Hat Advanced Cluster Management for Kubernetes 2.14; Red Hat Advanced Cluster Management for Kubernetes 2.15; and 2 more.
Medium [CVE-2026-73283] Tunnel forwarding restriction bypass
In sshd in OpenSSH before 10.5, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not. The `restrict` keyword, designed to limit tunnel forwarding within the `authorized_keys` file, was not correctly enforced for tunnel forwarding. This issue could allow a local attacker to bypass intended security restrictions, potentially leading to unauthorized network access or resource usage through tunnels. An authorization bypass flaw was found in OpenSSH's sshd daemon. When processing SSH public key authentication, sshd fails to enforce the restrict keyword in authorized_keys against TUN/TAP tunnel forwarding requests. An authenticated user holding a restricted key can still establish virtual network interface tunnels if tunnel forwarding is globally enabled on the server. This allows authorized users to bypass intended per-key restriction policies, posing a Moderate impact to confidentiality and integrity. Red Hat severity: Moderate — CVSS 5.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N). Weakness: CWE-305. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat Hardened Images; Red Hat Update Infrastructure 5; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8. Red Hat fixing advisory: RHSA-2026:69129, RHSA-2026:69130, RHSA-2026:70719, RHSA-2026:71603.
Medium [CVE-2026-73282] Information disclosure and data corruption via use-after-free in ssh client
In ssh in OpenSSH before 10.5, a use-after-free for realloc data can occur if a certain pair of remote-forwarding operations are concurrent. A flaw was found in OpenSSH. This can occur if a remote forwarding is added via the local session multiplexing socket while a remote forwarding open request is pending with the server. A remote attacker with high attack complexity could potentially exploit this to achieve low impact on confidentiality and integrity. Red Hat severity: Moderate — CVSS 5.6 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Hardened Images; Red Hat Update Infrastructure 5; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat OpenShift Container Platform 4. Red Hat fixing advisory: RHSA-2026:69129, RHSA-2026:76748, RHSA-2026:69266, RHSA-2026:69130, RHSA-2026:70719, RHSA-2026:71603. Affected products named by the advisory: Red Hat package: openssh.
Medium [CVE-2026-73229] Django REST framework: Information disclosure via improper permission checks in AdminRenderer
Django REST framework is a powerful and flexible toolkit for building Web APIs. Prior to 3.17.2, Django REST Framework's rest_framework/renderers.py AdminRenderer.render() uses override_method() to simulate GET and directly invokes view.get() without view.check_permissions() while rendering an invalid write request, allowing a 400 Bad Request HTML response to disclose data from a GET representation that the requester is not permitted to access. This issue is fixed in version 3.17.2. The AdminRenderer component, when processing an invalid write request, can improperly invoke a GET request without adequate permission checks. This oversight allows an unauthenticated attacker to access data that they are not authorized to view, leading to information disclosure. This vulnerability affects the confidentiality of sensitive information. Red Hat severity: Moderate — CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-425. Affected Red Hat products: Red Hat Ansible Automation Platform 2; Red Hat Discovery 2; Red Hat Satellite 6; Red Hat Update Infrastructure 4 for Cloud Providers; Red Hat Update Infrastructure 5. Will not fix / out of support: Red Hat Ansible Automation Platform 2; Red Hat Update Infrastructure 4 for Cloud Providers. Red Hat does not currently list a fixing RHSA for this CVE.
