Summary

Distribution is a toolkit to pack, ship, store, and deliver container content. Prior to 3.1.1, tag deletion via the DELETE /v2/<name>/manifests/<tag> endpoint bypasses the storage.delete.enabled: false configuration, allowing any API client to remove tags from repositories even when the operator has explicitly disabled deletion. This vulnerability is fixed in 3.1.1.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
