The statically-linked gRPC stack in ml-metadata is outdated, making it vulnerable to known HTTP/2 denial of service (DoS) issues.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.","state":0,"publishedAt":"2026-08-10T20:45:38.918+00:00","modifiedAt":"2026-10-19T11:45:23.581+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"rhoai/odh-mlmd-grpc-server-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n
