CVE-2026-33581Network attack vector

Arbitrary file read via unvalidated media aliases

Published Mar 31, 2026 · Updated Mar 31, 2026

Path traversal in OpenClaw before 2026.3.24 allows remote authenticated users to read arbitrary local files through message tool aliases. The message-action parameter normalizer applies localRoots sandbox checks to canonical media keys but omits the mediaUrl and fileUrl aliases. A caller with low-privilege message-tool access can route either alias outside permitted media roots, exposing host files without write access.
