CVE-2026-28462

OpenClaw < 2026.2.13 - Path Traversal in Trace and Download Output Paths

8.7 HighFix available

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.

OpenClaw has a path traversal in browser trace/download output paths may allow arbitrary file writes

Summary

OpenClaw’s browser control API accepted user-supplied output paths for trace/download files without consistently constraining writes to OpenClaw-managed temporary directories.

Impact

If an attacker can access the browser control API, they could attempt to write trace/download output files outside intended temp roots, depending on process filesystem permissions.

Affected versions

openclaw < 2026.2.13

Fixed versions

openclaw >= 2026.2.13

Remediation

Upgrade to 2026.2.13 or later.

What changed

The fix constrains output paths for:

  • POST /trace/stop
  • POST /wait/download
  • POST /download

All three now enforce OpenClaw temp-root boundaries and reject traversal/escape paths.
