[openclaw] OpenClaw safeBins file-existence oracle information disclosure

**[openclaw] OpenClaw safeBins file-existence oracle information disclosure**

An 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...
