High [CVE-2026-0980] Rubyipmi: red hat satellite: remote code execution in rubyipmi via malicious bmc username
A flaw was found in rubyipmi, a gem used in the Baseboard Management Controller (BMC) component of Red Hat Satellite. An authenticated attacker with host creation or update permissions could exploit this vulnerability by crafting a malicious username for the BMC interface. This could lead to remote code execution (RCE) on the system. This vulnerability is rated Moderate for Red Hat Satellite because it requires the BMC component to be enabled and configured to use `ipmitool` as the IPMI implementation. Exploitation is limited to environments meeting these specific configuration and permission requirements. Red Hat severity: Moderate — CVSS 8.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L). Weakness: CWE-78. Affected Red Hat products: Red Hat Satellite 6.16 for RHEL 8; Red Hat Satellite 6.16 for RHEL 9; Red Hat Satellite 6.17 for RHEL 9; Red Hat Satellite 6.18 for RHEL 9; Red Hat Satellite 6. Red Hat fixing advisory: RHSA-2026:5971, RHSA-2026:5970, RHSA-2026:5968.

Medium [CVE-2025-13327] Uv: uv: specially crafted zip archives lead to arbitrary code execution due to parsing differentials
A flaw was found in uv. This vulnerability allows an attacker to execute malicious code during package resolution or installation via specially crafted ZIP (Zipped Information Package) archives that exploit parsing differentials, requiring user interaction to install an attacker-controlled package. This vulnerability is rated Moderate for Red Hat products. It allows arbitrary code execution through specially crafted ZIP archives when using the `uv` tool to install attacker-controlled Python packages. Exploitation requires user interaction to initiate the package installation. This affects components within Red Hat AI Inference Server and Red Hat OpenShift AI. Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-1286. Affected Red Hat products: Red Hat AI Inference Server; Red Hat OpenShift AI (RHOAI). Red Hat lists Red Hat AI Inference Server as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2025-9909] Aap-gateway: improper path validation in gateway allows credential exfiltration
A flaw was found in the Red Hat Ansible Automation Platform Gateway route creation component. This vulnerability allows credential theft via the creation of misleading routes using a double-slash (//) prefix in the gateway_path. A malicious or socially engineered administrator can configure a honey-pot route to intercept and exfiltrate user credentials, potentially maintaining persistent access or creating a backdoor even after their permissions are revoked. This issue is classified as Moderate because exploitation requires the attacker to have administrative access (or successfully social engineer a legitimate admin). A malicious or tricked admin can create a deceptive route with a double-slash path that captures user credentials in cleartext, potentially allowing persistent backdoor access even after the admin’s permissions are revoked. The gateway does not normalize or validate these paths, meaning normal users cannot detect the attack through ordinary API use. Although an attacker cannot exploit this without access to route creation, the combination of privileged requirements and complete credential exposure makes this a moderate severity risk in any environment where multiple users rely on gateway authentication. Red Hat severity: Moderate — CVSS 6.7 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-647.
Medium [CVE-2025-9908] Event-driven-ansible: sensitive internal headers disclosure in aap eda event streams
A flaw was found in the Red Hat Ansible Automation Platform, Event-Driven Ansible (EDA) Event Streams. This vulnerability allows an authenticated user to gain access to sensitive internal infrastructure headers (such as X-Trusted-Proxy and X-Envoy-*) and event stream URLs via crafted requests and job templates. By exfiltrating these headers, an attacker could spoof trusted requests, escalate privileges, or perform malicious event injection. This issue is classified as Moderate because the exposure of sensitive internal headers, including X-Trusted-Proxy and X-Envoy-* values, can lead to privilege escalation, request spoofing, and unauthorized access to internal infrastructure details. Exploitation requires low-complexity conditions and local access—any user with an EDA credential or shared access to a job template and event stream can capture these headers once an event is sent. The persistence of captured headers further increases risk, as sensitive values remain accessible to the attacker until explicitly cleared. Red Hat severity: Moderate — CVSS 6.7 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-200. Affected products named by the advisory: Red Hat Ansible Automation Platform 2.5 for RHEL 8; Red Hat Ansible Automation Platform 2.5 for RHEL 9; Red Hat Ansible Automation Platform 2.6 for RHEL 9.
Medium [CVE-2025-9907] Event-driven-ansible: event stream test mode exposes sensitive headers in aap eda
A flaw was found in the Red Hat Ansible Automation Platform, Event-Driven Ansible (EDA) Event Stream API. This vulnerability allows exposure of sensitive client credentials and internal infrastructure headers via the test_headers field when an event stream is in test mode. The possible outcome includes leakage of internal infrastructure details, accidental disclosure of user or system credentials, privilege escalation if high-value tokens are exposed, and persistent sensitive data exposure to all users with read access on the event stream. This issue is classified as Moderate because the exposure of sensitive headers, including client Authorization tokens and internal infrastructure values such as X-Trusted-Proxy, can lead to credential leakage and privilege escalation only after user forced mistake and with specific configuration. Exploitation does not require complex conditions—any user with read access to the event stream can retrieve the headers once a request has been posted in test mode. Exploitation depends on either a user mistakenly sending credentials to the event stream endpoint or internal headers being injected when the wrong path is used. The persistence of captured headers further increases risk, as sensitive values remain accessible until explicitly overwritten or deleted. Red Hat severity: Moderate — CVSS 6.7 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Low [CVE-2025-12150] webauthn attestation statement verification bypass
A flaw was found in Keycloak’s WebAuthn registration component. This vulnerability allows an attacker to bypass the configured attestation policy and register untrusted or forged authenticators via submission of an attestation object with fmt: "none", even when the realm is configured to require direct attestation. This can lead to weakened authentication integrity and unauthorized authenticator registration. Affected products named by the advisory: Red Hat build of Keycloak 26.2; Red Hat build of Keycloak 26.4.
High [CVE-2026-27970] @angular/core: Angular: Cross-site scripting via compromised translation files
