Critical [CVE-2026-51992] Arbitrary code execution via SQL Injection in create dictionaries function
Arbitrary code execution via SQL Injection in create dictionaries function. Red Hat rates this critical (CVSS 9.8). Weakness: CWE-89.
Critical [CVE-2026-44210] Privilege escalation and information disclosure via command-line argument injection
Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. Versions prior to 3.31.0 ship with a default configuration that allows pod creators to inject arbitrary command-line arguments into the virtiofsd process through the `io.katacontainers.config.hypervisor.virtio_fs_extra_args` pod annotation. By injecting `-o source=/` along with `--no-announce-submounts` and `--sandbox=none`, an attacker can override the virtiofsd shared directory to serve the entire host root filesystem into the guest VM. Combined with the `kernel_params` annotation (also enabled by default) to activate the agent debug console, the attacker can mount the host filesystem from inside the VM and read or write any file on the host, including /etc/shadow. Version 3.31.0 patches the issue. A user with privileges to create pods can inject malicious command-line arguments into the virtiofsd process, which manages shared file systems. When combined with another default configuration, this vulnerability allows an attacker to read and write any file on the host system, leading to significant information disclosure and potential privilege escalation. Red Hat severity: Important — CVSS 9.9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). Weakness: CWE-88. Affected Red Hat products: Red Hat OpenShift Container Platform 4.
Critical [CVE-2026-65601] Privilege Escalation via Kubernetes Gateway API Namespace Confusion
Traefik versions 3.7.0 through 3.7.6 contain a namespace confusion vulnerability in the Kubernetes Gateway API provider. When resolving HTTPRoute.spec.rules[].backendRefs[].filters[].extensionRef, Traefik used the backend Service namespace instead of the HTTPRoute namespace. A low-privileged route author holding a ReferenceGrant for a cross-namespace Service could therefore bind a Traefik Middleware from the backend namespace without a separate grant for that middleware, potentially injecting trusted reverse-proxy identity headers into downstream requests. The issue is fixed in version 3.7.7. A flaw was found in Traefik, a cloud-native edge router. This flaw allows an attacker to bypass security controls by incorrectly binding a Traefik Middleware from a different namespace, potentially leading to the injection of trusted identity headers into network requests. This could result in unauthorized access or privilege escalation within the Kubernetes cluster. This is an Important flaw in Traefik's Kubernetes Gateway API provider, affecting Red Hat OpenShift Dev Spaces. A low-privileged user in a Kubernetes environment can exploit a namespace confusion vulnerability to bypass security controls. Red Hat severity: Important — CVSS 9.6 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N). Weakness: CWE-348. Affected Red Hat products: Red Hat OpenShift Dev Spaces 3.30.
Critical [CVE-2026-65600] Authentication bypass via path traversal in ReplacePathRegex middleware
Traefik versions = v3.6.0 = v3.7.0 <= v3.7.6 contain an authentication bypass via path traversal in the ReplacePathRegex middleware. When ReplacePathRegex is configured with a regex that captures user-controlled path segments without a mandatory path separator (e.g. regex "^/api(.*)", replacement "/$1"), the middleware forwards the replaced path to the backend without validating that it matches its normalized form. An unauthenticated remote attacker can send a crafted request (e.g. GET /api../admin) that produces an un-normalized path such as /../admin, which a backend that normalizes paths resolves to a protected route, bypassing authentication middleware. Fixed in v2.11.52, v3.6.23, and v3.7.7. A flaw was found in Traefik. When this middleware is misconfigured, it forwards un-normalized paths, allowing a backend to resolve them to protected routes and grant unauthorized access. This bypass enables access to sensitive administrative interfaces. This Critical flaw in Traefik's `ReplacePathRegex` middleware allows an unauthenticated remote attacker to bypass authentication. The impact to OpenShift Dev Spaces is rated as low, because the affected `ReplacePathRegex` middleware is not configured in the shipped Traefik gateway. Red Hat severity: Critical — CVSS 10 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N). Weakness: CWE-22.
Critical [CVE-2026-64193] Net::DNS: Net::DNS: Arbitrary code execution via EDNS EXTENDED ERROR handling
Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR. Net::DNS::RR::OPT::EXTENDED_ERROR::_decompose parses the EXTRA-TEXT field of an EDNS EXTENDED-ERROR option (RFC 8914) by tokenising the raw bytes and passing the result to Perl's eval. There is some escaping done for $ and @, but not for backticks. This can be exploited for command execution if $pkt->edns->option('EXTENDED-ERROR') is called in array context, for example with a payload of {0:`""`} in EXTRA-TEXT. The affected component processes the `EXTRA-TEXT` field of an EDNS EXTENDED-ERROR option without properly escaping special characters, which allows for command injection. This enables an attacker to execute unauthorized commands on the system. Red Hat severity: Critical — CVSS 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-78. 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.
Critical [CVE-2026-12701] relative_path_validator bypass via directory traversal in FilesystemExport
A path traversal vulnerability was found in pulpcore. The relative_path_validator function only verifies that content paths do not begin with "/" but fails to block directory traversal sequences such as "../" anywhere in the path. An authenticated administrator can craft a relative_path containing embedded traversal sequences (e.g., "looking/normal/../../../../etc/shadow") that escapes the intended export directory during FilesystemExport operations. Because the file content is also user-controlled (uploaded artifact), this allows arbitrary file write to any location writable by the Pulp service user, potentially leading to service compromise or further system exploitation. This vulnerability is rated as Important severity because an authenticated administrator can achieve arbitrary file write outside the intended export directory with fully attacker-controlled content. The FilesystemExport API is restricted to admin-level users (in Satellite, authenticated via SSL certificate; in standalone RBAC deployments, admin role only). The Pulp process runs as the "pulp" system user (not root), and file permission bits cannot be controlled by the attacker.
Critical [CVE-2026-16242] Konnectivity proxy-server accepts agent connections without validating client certificates
A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic. Because that endpoint is exposed so worker agents can connect, a successful attack can enroll an untrusted agent in the routing pool. When the proxy selects that stream for a control-plane dial, the attacker may proxy, inspect, modify, or drop control-plane-to-node traffic, affecting confidentiality, integrity, and availability of that path. Red Hat severity: Critical — CVSS 9.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L). Weakness: CWE-306. Affected products named by the advisory: multicluster engine for Kubernetes 2.11; multicluster engine for Kubernetes 2.17; multicluster engine for Kubernetes 2.6; multicluster engine for Kubernetes 2.8; and 10 more.
Critical [CVE-2026-15773] Use after free in Core

Red Hat severity: Important — CVSS 9.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N). Weakness: CWE-346.
Critical [CVE-2026-15774] Use after free in Skia
Use after free in Skia in Google Chrome prior to 150.0.7871.125 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High) Upstream bug(s): Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory. Red Hat severity: Important — CVSS 9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat fixing advisory: RHSA-2026:74084. Affected products named by the advisory: Red Hat package: webkit2gtk3; Red Hat package: webkitgtk4.
Critical [CVE-2026-54058] Memory disclosure or denial of service via crafted McIdas AREA image
Pillow is a Python imaging library. Prior to 12.3.0, when Pillow loads an uncompressed McIdas AREA image from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width, causing pixel access such as Image.tobytes(), getpixel, convert, or save to read beyond the mapped region and disclose adjacent process memory or fault. This issue is fixed in version 12.3.0. A remote attacker who can supply such an image to a service that loads it without user interaction may disclose adjacent process memory or trigger a denial of service. Red Hat severity: Important — CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H). Weakness: CWE-125. Affected products named by the advisory: Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On; Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On; and 22 more.
Critical [CVE-2026-57211] Information disclosure via path validation bypass in management plugin
RabbitMQ is a messaging and streaming broker. Prior to 4.1.11 and 4.2.6 on Windows, the RabbitMQ management plugin static file handler rabbit_mgmt_wm_static can pass URL-encoded backslashes to erl_prim_loader:read_file_info before path validation when multiple management extension plugins are enabled, causing outbound DNS and SMB requests to attacker-controlled UNC paths. This issue is fixed in versions 4.1.11 and 4.2.6. A flaw was found in RabbitMQ. This can lead to outbound DNS and Server Message Block (SMB) requests to attacker-controlled network paths, potentially disclosing sensitive information. Red Hat severity: Critical — CVSS 10 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). Weakness: CWE-76. Affected Red Hat products: Red Hat Hardened Images. Red Hat lists Red Hat OpenStack Platform 16.2; Red Hat OpenStack Platform 17.1; Red Hat OpenStack Platform 18.0 as not affected. Red Hat fixing advisory: RHSA-2026:35939, RHSA-2026:35940.
Critical [CVE-2026-15143] SSRF and local file read via user-supplied XML Schema (xml-with-schema:)
A flaw was found in the file_type content detector of guardrails-detectors. This vulnerability allows a remote attacker to supply an arbitrary XML Schema Definition (XSD) string, which is processed without proper restrictions. This can lead to server-side requests to arbitrary URLs or local file reads, potentially resulting in sensitive information disclosure, such as cloud provider credentials or access to internal network services. This vulnerability is rated as Important. It allows an attacker with network access to the detector service to perform Server-Side Request Forgery (SSRF) and local file reads. This is due to the guardrails-detectors component accepting arbitrary XML Schema Definition (XSD) strings, which are then processed by the xmlschema library without restricting external schemaLocation references. Red Hat severity: Important — CVSS 9.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N). Weakness: CWE-918. Affected Red Hat products: Red Hat OpenShift AI (RHOAI). Red Hat does not currently list a fixing RHSA for this CVE.
Critical [CVE-2026-15378] SSRF and local file read via user-supplied XML Schema (xml-with-schema:)
A flaw was found in the `guardrails-detectors` component. This vulnerability allows a remote attacker to perform a blind Server-Side Request Forgery (SSRF) by submitting a specially crafted XML Schema Definition (XSD) string. This can lead to unauthorized access to sensitive information, including credentials from cloud metadata services, Kubernetes API, internal MinIO, and other internal network endpoints. Additionally, it enables local file reads of critical data such as service account tokens and pod secrets. Red Hat severity: Important — CVSS 9.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N). Weakness: CWE-918. Affected Red Hat products: Red Hat OpenShift AI 2.25; Red Hat OpenShift AI 3.3; Red Hat OpenShift AI 3.4. Red Hat fixing advisory: RHSA-2026:65126, RHSA-2026:73987, RHSA-2026:60520.
