The statically-linked gRPC stack in ml-metadata is outdated, making it vulnerable to known HTTP/2 denial of service (DoS) issues. An in-cluster attacker, with network access to the MLMD pod, could exploit these vulnerabilities by sending specially crafted HTTP/2 requests. This could lead to a denial of service by crashing the MLMD pod, disrupting all pipeline runs in the affected namespace.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:53261** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-08-11 · [advisory](https://access.redhat.com/errata/RHSA-2026:53261)\n- **RHSA-2026:53263** · Red Hat · fixed in: Red Hat OpenShift AI 3.3 · released 2026-08-11 · [advisory](https://access.redhat.com/errata/RHSA-2026:53263)\n- **RHSA-2026:53262** · Red Hat · fixed in: Red Hat OpenShift AI 3.4 · released 2026-08-11 · [advisory](https://access.redhat.com/errata/RHSA-2026:53262)\n- **RHSA-2026:60367** · Red Hat · fixed in: Red Hat OpenShift AI 3.5 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60367)","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
