Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.31

Description A local roots self-whitelisting issue exists in the appendLocalMediaParentRoots() function. This flaw allows for model-initiated arbitrary host file read due to improper validation of the media parent directory, which could enable attackers to exfiltrate credentials and access sensitive files.

Recommendations Update to version 2026.3.31 or later. As a temporary workaround, restrict access to the appendLocalMediaParentRoots() function to minimize the risk of exploitation.
