CVE-2026-28462: OpenClaw has a path traversal in browser trace/download output paths may allow arbitrary file writes

highCVSS 4.0 8.7 · 3.1 7.5GHSA-gq9c-wg68-gwj2

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.

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.
