{"id":"CVE-2026-35172","aliases":["GHSA-f2g3-hh2r-cwgc"],"url":"https://o3.security/vulnerability/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.","published":"2026-04-06T19:08:44.512Z","modified":"2026-08-07T11:50:56.067367775Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/distribution/distribution/v3","fixedVersion":"3.1.0"},{"ecosystem":"Go","name":"github.com/distribution/distribution","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-35172.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:23234"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:25045"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26529"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:26543"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:28893"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:37387"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-35172"},{"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"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2455571"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:56.067367775Z"}}
