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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-354"],"references":["https://github.com/distribution/distribution/commit/960439b09f342cdeb8f1c0e18e8c7349bdcfbf80","https://github.com/distribution/distribution/releases/tag/v3.1.2","https://github.com/distribution/distribution/security/advisories/GHSA-685w-q87j-wqw3","https://github.com/distribution/distribution/security/advisories/GHSA-685w-q87j-wqw3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:59:28.494260111+00:00"},"epss":{"cve":"CVE-2026-85747","score":0.00218,"percentile":0.12133,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-685w-q87j-wqw3","url":"https://osv.dev/vulnerability/GHSA-685w-q87j-wqw3","summary":"Distribution: Client `manifests.Get()` does not verify returned content against requested digest","modified":"2026-10-20T10:41:04.049860645Z","packages":[{"ecosystem":"Go","name":"github.com/docker/distribution","purl":"pkg:golang/github.com/docker/distribution","ranges":["<=2.8.3"],"fixed":[]},{"ecosystem":"Go","name":"github.com/distribution/distribution/v3","purl":"pkg:golang/github.com/distribution/distribution/v3","ranges":["<3.1.2"],"fixed":["3.1.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
