OpenClaw versions prior to 2026.2.13 contain a vulnerability in the browser control API in which it accepts user-supplied output paths for trace and download files without consistently constraining writes to temporary directories. Attackers with API access can exploit path traversal in POST /trace/stop, POST /wait/download, and POST /download endpoints to write files outside intended temp roots.
