BREW-OPENCLAW-CLI-CVE-20… (GHSA-MWCG-WFQ3-4GJC)
Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-17 17:24 – Source websiteSummary
In openclaw@2026.2.24, approval-bound system.run on node hosts could be influenced by mutable symlink cwd targets between approval and execution.
Details
Approval matching on the gateway validated command/argv and binding fields, including cwd, as provided text. Node execution later used runtime cwd resolution. A symlinked cwd could therefore be retargeted after approval and before spawn.
OpenClaw's trust model does not treat one shared gateway as a multi-tenant adversarial boundary, but approval integrity is still a security boundary for operator-reviewed command execution.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected:
<= 2026.2.24 - Patched:
>= 2026.2.25
Fix Commit(s)
f789f880c934caa8be25b38832f27f90f37903db
Remediation
The fix adds defense-in-depth hardening for approval-bound node execution:
- reject symlink cwd paths for approval-bound system.run
- canonicalize path-like executable argv before spawn
- bind CLI approval requests to exact commandArgv
Release Process Note
Patched version is pre-set to the release (2026.2.25). Advisory published with npm release 2026.2.25.
OpenClaw thanks @tdjackey for reporting.
