OpenClaw has browser trace/download path symlink escape in temp output handling

Summary

Browser trace/download output path handling allowed symlink-root and symlink-parent escapes from the managed temp root.

Affected Packages / Versions

• Package: openclaw (npm)
• Latest published npm version: 2026.2.24
• Affected versions: <= 2026.2.24
• Planned patched release: 2026.2.25

Impact

An attacker with relevant local foothold and ability to influence output paths could route writes outside the intended temp root via symlink traversal, leading to arbitrary file overwrite.

Release Process Note

patched_versions is pre-set to the release (2026.2.25) so once npm 2026.2.25 is published, the advisory is published.

OpenClaw thanks @tdjackey for reporting.
