Prior to 3.1.2, registry/client.(*manifests).Get() reads a manifest returned for a digest-pinned request and passes it to distribution.UnmarshalManifest without hashing the body against the requested digest, allowing a malicious or intercepted registry response to substitute attacker-chosen manifest content even when Docker-Content-Digest claims the requested value. The bundled pull-through proxy in registry/proxy/proxymanifeststore.go can cache and re-serve the substituted manifest. This issue is fixed in version 3.1.2.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-85747)\n\nAffected packages:\n\n- `github.com/docker/distribution <= 2.8.3`\n- `github.com/distribution/distribution/v3 < 3.1.2`\n\nPatched in:\n\n- `github.com/distribution/distribution/v3 3.1.2`\n\nSource: https://github.com/advisories/GHSA-685w-q87j-wqw3","depth":"twilight","depthScore":49,"depthScoreParts":{"impact":37.4,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":224423,"id":"CVE-2026-85747","ts":1792331050830,"field":"exploit_available","old":"false","new":"true"}]}
