1) Improper Authorization (CVE-ID: CVE-2026-41888)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote user to bypass authorization checks.

The vulnerability exists due to improper access control in the DELETE /v2//manifests/ endpoint when handling tag deletion requests. A remote API client can send a crafted DELETE request for a tag reference to remove tags from repositories even when the operator has explicitly disabled deletion.
