Summary
OpenClaw's sandbox bind validation could bypass allowed-root and blocked-path checks via symlink-parent missing-leaf paths
Details

Summary

In openclaw up to and including 2026.2.23 (latest npm release as of February 24, 2026), sandbox bind-source validation could be bypassed when a bind source used a symlinked parent plus a non-existent leaf path.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.23
  • Patched: >= 2026.2.24 (planned next release)

Root Cause

validateBindMounts previously relied on full-path realpath only when the full source path already existed. For missing-leaf paths, parent symlink traversal was not fully canonicalized before allowed-root and blocked-path checks.

Security Impact

A source path that looked inside an allowed root could resolve outside that root (including blocked runtime paths) once the missing leaf was created, weakening sandbox bind-source boundary enforcement.

Fix

The validation path now canonicalizes through the nearest existing ancestor, then always re-checks the canonical path against both:

  • allowed source roots
  • blocked runtime paths

Verification

  • pnpm check
  • pnpm exec vitest run --config vitest.gateway.config.ts
  • pnpm test:fast
  • Added regression tests for symlink-parent + missing-leaf bypass patterns.

Release Process Note

patched_versions is pre-set to the planned next release (2026.2.24) so after npm publish the advisory can be published without further field edits.

OpenClaw thanks @tdjackey for reporting.
