Summary
OpenClaw: Unified root-bound write hardening for browser output and related path-boundary flows
Details

Summary

A path-confinement bypass in browser output handling allowed writes outside intended roots in openclaw versions up to and including 2026.3.1.

The fix unifies root-bound, file-descriptor-verified write semantics and canonical path-boundary validation across browser output and related install/skills write paths.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version at triage time: 2026.3.1
  • Affected range: <= 2026.3.1
  • Patched release: 2026.3.2 (released)

Fix Commit(s)

  • 104d32bb64cdf19d5e77f70553a511a2ae90ad1c

Technical Notes

  • Browser output writes now use root-bound, fd/inode-verified commit flow.
  • Install + skills path checks now share canonical in-base validation to reduce drift and close equivalent escape surfaces.
  • Added regression coverage for symlink-rebind and root-bound source-path write behavior.
Severity
5.3 (Medium)
