Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-41908 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2026-41908 actively exploited in the wild?

Description

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.
