{"id":"CVE-2026-35172","summary":"Distribution has stale blob access resurrection via repo-scoped redis descriptor cache invalidation","details":"Distribution is a toolkit to pack, ship, store, and deliver container content. 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.","aliases":["GHSA-f2g3-hh2r-cwgc"],"modified":"2026-04-13T04:27:55.803919Z","published":"2026-04-06T19:08:44.512Z","related":["CGA-5r6m-hcwc-jvhp"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35172.json","cwe_ids":["CWE-284"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35172.json"},{"type":"ADVISORY","url":"https://github.com/distribution/distribution/security/advisories/GHSA-f2g3-hh2r-cwgc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35172"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/distribution/distribution","events":[{"introduced":"0"},{"fixed":"708f8d6b060248fe7192294dd5440320ffc86da0"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.1.0"}],"source":"AFFECTED_FIELD"}}],"versions":["docs-v2.4.1-2016-06-28","v2.0.0","v2.0.0-alpha.0","v2.0.0-alpha.1","v2.0.0-alpha.2","v2.0.0-alpha.3","v2.0.0-rc.0","v2.0.0-rc.1","v2.0.0-rc.2","v2.0.0-rc.3","v2.0.0-rc.4","v2.1.0","v2.1.0-rc.0","v2.1.1","v2.2.0","v2.2.1","v2.3.0-alpha","v2.3.0-rc.0","v2.3.0-rc.1","v2.3.0-rc.2","v2.4.0-rc.1","v2.5.0-rc.1","v2.6.0-rc.1","v2.7.0","v2.7.0-rc.0","v3.0.0","v3.0.0-alpha.1","v3.0.0-beta.1","v3.0.0-rc.1","v3.0.0-rc.2","v3.0.0-rc.3","v3.0.0-rc.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-35172.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
