Release of RHOAI 3.4.4 provides these changes:

Red Hat OpenShift AI version 3.4.3 addresses multiple security issues identified by CVE-2026-13717 and others. The advisory announces updated images for Red Hat OpenShift AI to mitigate these vulnerabilities. The update is critical and users are advised to upgrade their clusters following Red Hat's official documentation. No specific technical details or exploit information are provided in the advisory.

A critical vulnerability (CVE-2026-14450) exists in the MaaS API that allows any pod within a Kubernetes cluster to bypass the Kuadrant AuthPolicy gateway by forging HTTP headers (X-MaaS-Username and X-MaaS-Group). This authentication bypass enables unauthorized access and privilege escalation, including minting Kubernetes ServiceAccount tokens in other tenants' namespaces, revoking API keys, and exfiltrating sensitive configuration data. The vulnerability has a CVSS score of 9.9 and is classified as an authentication bypass (CWE-290).

A flaw was found in the MaaS API. This vulnerability allows any pod within the cluster to bypass the Kuadrant AuthPolicy gateway by forging HTTP headers, specifically `X-MaaS-Username` and `X-MaaS-Group`, which are trusted verbatim. This lack of first-party authentication enables an attacker to gain unauthorized access and escalate privileges. The concrete consequences include the ability to mint Kubernetes ServiceAccount tokens in other tenants' namespaces, revoke API keys, and exfiltrate sensitive model access configuration.

The RHTAS Operator can be used with OpenShift Container Platform 4.16, 4.17, 4.18, 4.19, 4.20 and 4.21

The fence-agents packages provide a collection of scripts for handling remote power management for cluster devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster. Security Fix(es): * urllib3: urllib3 Streaming API improperly handles highly compressed data (CVE-2025-66471) * urllib3: urllib3 vulnerable to decompression-bomb safeguard bypass when following HTTP redirects (streaming API) (CVE-2026-21441) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
