GHSA-6C9J-X93C-RW6J
Vulnerability from github – Published: 2026-02-19 22:06 – Updated: 2026-02-19 22:06An information disclosure vulnerability in OpenClaw's tools.exec.safeBins approval flow allowed a file-existence oracle.
When safe-bin validation examined candidate file paths, command allow/deny behavior could differ based on whether a path already existed on the host filesystem. An attacker could probe for file presence by comparing outcomes for existing vs non-existing filenames.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.17 - Latest published vulnerable version at triage time:
2026.2.17 - Planned patched version:
2026.2.19
Impact
Attackers with access to this execution surface could infer whether specific files exist (for example secrets/config files), enabling filesystem enumeration and improving follow-on attack planning.
Fix
The safe-bin policy was changed to deterministic argv-only validation without host file-existence checks. File-oriented flags are blocked for safe-bin mode (for example sort -o, jq -f, grep -f), and trusted-path checks remain enforced.
