OpenClaw: safeBins static default trusted dirs allow writable-dir binary hijack (`jq`)

Summary

In openclaw<=2026.2.23, safe-bin trust in allowlist mode relied on static default trusted directories that included package-manager paths (notably /opt/homebrew/bin and /usr/local/bin). When a same-name binary (for example jq) is placed in one of those trusted default directories, safe-bin evaluation can be satisfied and execute the attacker-controlled binary.

Impact

This is an exec allowlist safeBins policy bypass that can lead to command execution in the OpenClaw runtime context. Severity is set to Medium given the required ability to write into trusted host binary directories.

Affected Packages / Versions

• Package: openclaw (npm)
• Vulnerable versions: <= 2026.2.23
• Patched versions: >= 2026.2.24 (planned next npm release)
• Latest published npm version at triage time (2026-02-24): 2026.2.23

Root Cause

• Default safe-bin trusted directories included package-manager/user-managed paths.
• Trust decision was directory-membership only for resolved executable paths.

Remediation

• Restrict default safe-bin trusted directories to immutable system paths: /bin, /usr/bin.
• Require explicit operator opt-in for package-manager/user paths via tools.exec.safeBinTrustedDirs.
