Official description

OpenClaw before 2026.3.22 contains a path traversal vulnerability in Windows media loaders that accepts remote-host file URLs and UNC-style paths before local-path validation. Attackers can exploit this by providing network-hosted file targets that are treated as local content, bypassing intended access restrictions.
