Prior to 3.1.0, distribution can restore read access in repo a after an explicit delete when storage.cache.blobdescriptor: redis and storage.delete.enabled: true are both enabled. The delete path clears the shared digest descriptor but leaves stale repo-scoped membership behind, so a later Stat or Get from repo b repopulates the shared descriptor and makes the deleted blob readable from repo a again. This vulnerability is fixed in 3.1.0."}], "lastModified": "2026-04-27T23:55:02.720", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:distribution:distribution:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B0361B73-DBB7-4E06-9F20-D9EE6C841671", "versionEndExcluding": "3.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
