Aliases CVE-2026-41908
Summary OpenClaw: Assistant media route missed scope enforcement for trusted-proxy authorization ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `< 2026.4.20` - Patched version: `2026.4.20` ## Impact The Control UI assistant-media route authenticated trusted-proxy callers but did not enforce the declared operator scopes for identity-bearing HTTP auth paths. A trusted-proxy caller without `operator.read` could access assistant-media files and metadata that were otherwise inside allowed media roots. The route still required successful gateway authentication and media-root checks. Severity is low. ## Fix Assistant-media file and metadata requests now require `operator.read` on identity-bearing HTTP auth paths. Fix commit: - `99ef3a63c58440d53f8e45ad861b846032fcb036` ## Release Fixed in OpenClaw `2026.4.20`.
