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.","affected":[{"package":{"name":"distribution","ecosystem":"Bitnami","purl":"pkg:bitnami/distribution"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.1.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/distribution/BIT-distribution-2026-35172.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}],"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:23234"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:25045"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26529"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:26543"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:28893"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:37387"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-35172"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2455571"},{"type":"ADVISORY","url":"https://github.com/distribution/distribution/security/advisories/GHSA-f2g3-hh2r-cwgc"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35172"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-35172.json"}],"database_specific":{"cpes":["cpe:2.3:a:distribution:distribution:*:*:*:*:*:go:*:*"],"severity":"High"}}
