Doc Text:
A flaw was found in Distribution, a software toolkit used for managing container content. This vulnerability allows a remote attacker to bypass security settings designed to prevent the deletion of container tags. By sending a specific request, an attacker can remove tags from repositories even when the system administrator has explicitly disabled this function. This unauthorized action could lead to the removal of critical container references, potentially causing disruption or denial of service.

Description OSIDB Bzimport 2026-05-14 18:02:17 UTC
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.
