0 CVE-2026-45781 is a vulnerability in the modelcontextprotocol (MCP) registry prior to version 1.7.9. The issue arises because the OCI ownership validation fails open when the upstream OCI registry returns an HTTP 429 (Too Many Requests) response. This failure allows any authenticated publisher to bind namespaces they do not control to OCI images, bypassing the critical label-match ownership check. The vulnerability is specific to OCI packages; other package types enforce stricter validation. This flaw has a low severity score and no known exploits in the wild. A fix was introduced in version 1.7.9. Join the discussion | CVE Database V5 | 05/14/2026, 21:00:49 UTC Added: 05/14/2026, 21:22:34 UTC |
