CVE-2026-61833Public exploitNetwork attack vectorHinoki check available

Authenticated image deletion via collapsed bearer scopes

Published Sep 18, 2026 · Updated Sep 18, 2026

Improper authorization in The zot Project zot before 2.1.18 allows remote authenticated users to delete registry manifests and blobs. The bearer handler in pkg/api/authn.go maps DELETE to push, bypasses DistSpecAuthzHandler, and the deletion handlers do not recheck permission. A pull-and-push bearer token within a repository scope is sufficient to remove manifests and blobs, making images unavailable and altering history.
