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.
High [CVE-2026-5056] Arbitrary code execution via stack-based buffer overflow in qtdemux
GStreamer qtdemux Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of UncompressedFrameConfigBox structures. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29392. This occurs due to insufficient data length validation when parsing UncompressedFrameConfigBox structures. An Important security flaw in GStreamer's QuickTime parser could allow an attacker to execute malicious code if a user opens a specially crafted media file. Because the vulnerable code was introduced in GStreamer 1.26.0, Red Hat Enterprise Linux (RHEL) versions 9 and older do not contain this code and are not affected by this vulnerability. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-121. Red Hat fixing advisory: RHSA-2026:49508. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat package: gstreamer1-plugins-good.
High [CVE-2026-18022] Arbitrary Code Execution via Integer Wraparound
Integer wraparound in IVFFlat index build in pgvector before 0.8.6 allows a database user to write data out-of-bounds, which could lead to arbitrary code execution. Only 32-bit systems are affected. A flaw was found in pgvector. An integer wraparound vulnerability exists during the IVFFlat index build process. This flaw allows a database user on a 32-bit system to write data outside of allocated memory buffers. 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-787. Red Hat lists Lightspeed Core; OpenShift Lightspeed; Red Hat Ansible Automation Platform 2; Red Hat Enterprise Linux 9; Red Hat Trusted Profile Analyzer as not affected.
High [CVE-2026-67201] Server-Side Request Forgery (SSRF) bypass due to URL parser differential
V through 0.5.2, fixed in commit 85859f0, contains a server-side request forgery (SSRF) bypass vulnerability that allows attackers to circumvent host-based allowlists by exploiting a parser differential between net.urllib and net.http. Attackers can craft a URL containing a backslash in the authority section such that net.urllib.parse() extracts the trusted host for allowlist validation while net.http.get() normalizes the backslash and connects to the internal host, enabling access to internal network services that the allowlist was intended to block. A flaw was found in V, specifically within its `net.urllib` and `net.http` components. This vulnerability allows a remote attacker to bypass host-based allowlists by exploiting a difference in how URLs are parsed. By crafting a malicious URL with a backslash, an attacker can trick the system into validating a trusted host while actually connecting to an internal network service. This enables unauthorized access to internal resources that should otherwise be protected. This flaw allows a remote attacker to circumvent host-based allowlists by exploiting a URL parser differential, enabling unauthorized access to internal network services. Applications utilizing these components for URL validation and fetching are at risk of exposing internal resources.
High [CVE-2026-18255] Global read-only superuser can view robot account tokens
A flaw was found in Quay. A user configured in GLOBAL_READONLY_SUPER_USERS is able to view robot account tokens for repositories they are not a member of, allowing an attacker with read-only superuser privileges to impersonate any robot account. 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-863. Affected Red Hat products: Red Hat Quay 3.10; Red Hat Quay 3.12; Red Hat Quay 3.14; Red Hat Quay 3.15; Red Hat Quay 3.16; Red Hat Quay 3.17; Red Hat Quay 3.9. Red Hat fixing advisory: RHSA-2026:66084, RHSA-2026:66523, RHSA-2026:70267, RHSA-2026:63307, RHSA-2026:69255, RHSA-2026:74511, RHSA-2026:65514.
High [CVE-2026-13697] Information disclosure and Denial of Service via malformed Cache-Control directives
Information disclosure and Denial of Service via malformed Cache-Control directives. Red Hat rates this important (CVSS 7.4). Weakness: CWE-524. Red Hat lists fixing advisory RHSA-2026:48273 with package nodejs26-main-26.5.1-1.5.hum1, nodejs24-main-24.18.1-0.1.hum1.
High [CVE-2026-55707] Shared-network consumer can re-scope another project's subnets via subnetpool onboarding
In OpenStack Neutron before 28.0.2, the subnetpool onboarding API does not verify ownership of the target subnets. An authenticated user can onboard subnets from another project's shared network into their own subnetpool, mutating the victim's subnet state and altering L3 routing and address scope behavior for victim routers. An authorization bypass was found in the OpenStack Neutron subnetpool onboarding API endpoint (PUT /v2.0/subnetpools/{id}/onboard_network_subnets). When a caller supplies a network_id, the API only verifies that the network is visible to the caller but does not verify that the caller owns the subnets on that network. When a network is RBAC-shared or globally shared, any project member with network visibility can invoke the API to onboard another project's subnets into the caller's own subnetpool, mutating the victim's subnet records (setting subnetpool_id to the attacker-controlled pool). If the attacker's subnetpool is associated with an address scope, Neutron syncs the victim's router interfaces with the attacker-controlled address scope, silently altering L3 routing, NAT, and address-scope behavior. The upstream fix adds an ownership check ensuring the caller has admin-or-owner authority over each subnet being onboarded, not merely visibility of the parent network.
High [CVE-2026-55995] Denial of Service via double-free in iSNS attribute decoder
A Double Free vulnerability in open-iscsi allows an unauthenticated MITM attacker to cause DoS. This issue affects open-iscsi: from? through 56718d4e9d1a4f51c30697b5c0534144bb41c9bb. An unauthenticated man-in-the-middle (MITM) attacker can exploit a double-free vulnerability in the iSNS attribute decoder. This can lead to a denial of service (DoS) condition, making the affected system unavailable. The vulnerability is network-exploitable without requiring user interaction or authentication, posing a significant risk to the availability of iSNS services in environments where the `isns-utils` package is deployed and the iSNS service is exposed. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-763. Affected products named by the advisory: Red Hat Enterprise Linux 10.0 Extended Update Support; 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; and 7 more.
