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.","state":0,"publishedAt":"2026-10-13T18:20:56.539+00:00","modifiedAt":"2026-10-18T13:38:36.137+00:00","affected":[{"ecosystem":"Vendor product","name":"distribution","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"distribution\",\n                    \"product\": \"distribution\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.1.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/distribution/distribution/security/advisories/GHSA-685w-q87j-wqw3","https://github.com/distribution/distribution/commit/960439b09f342cdeb8f1c0e18e8c7349bdcfbf80","https://github.com/distribution/distribution/releases/tag/v3.1.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-85747","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-85747","identifiers":["CVE-2026-85747"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
