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.

CRITICALNVD 9.19.1
EchelonGraph scoreLOW confidence
This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
