{"id":"BIT-distribution-2026-85747","summary":"Distribution: Client `manifests.Get()` does not verify returned content against requested digest","details":"Distribution is a toolkit to pack, ship, store, and deliver container content. 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.","aliases":["CVE-2026-85747","GHSA-685w-q87j-wqw3"],"modified":"2026-10-20T10:41:04.049860645Z","published":"2026-10-20T08:39:45.031Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:distribution:distribution:*:*:*:*:*:go:*:*"]},"references":[{"type":"WEB","url":"https://github.com/distribution/distribution/commit/960439b09f342cdeb8f1c0e18e8c7349bdcfbf80"},{"type":"WEB","url":"https://github.com/distribution/distribution/releases/tag/v3.1.2"},{"type":"WEB","url":"https://github.com/distribution/distribution/security/advisories/GHSA-685w-q87j-wqw3"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85747"}],"affected":[{"package":{"name":"distribution","ecosystem":"Bitnami","purl":"pkg:bitnami/distribution"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.1.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/distribution/BIT-distribution-2026-85747.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N"}]}],"schema_version":"1.9.0"}
