  "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.", "A flaw was found in Distribution, a toolkit used for managing container content. When specific caching and deletion features are enabled, a remote attacker can exploit a vulnerability that allows previously deleted content to become readable again. This occurs because the system does not fully remove all references to the deleted data, leading to unauthorized information disclosure." ],
