CVE-2026-35172
Vulnerability Summary
Timeline
Description
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.
