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.
