Описание
OpenClaw exec allowlist safeBins short-option bypass could permit arbitrary file write
Summary
OpenClaw exec allowlist/safeBins policy could be bypassed with attached short-option payloads (for example sort -o/tmp/poc), enabling file-write operations while still satisfying safeBins checks.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.17 - Latest published vulnerable version:
2026.2.17 - Patched in:
2026.2.19
Impact
When tools.exec.security=allowlist and tools.exec.safeBins included affected binaries, attached short-option payloads could bypass safeBins argument validation and permit file-write behavior that should have been denied.

Связанные уязвимости
OpenClaw versions prior to 2026.2.19 contain an allowlist bypass vulnerability in the exec safeBins policy that allows attackers to write arbitrary files using short-option payloads. Attackers can bypass argument validation by attaching short options like -o to whitelisted binaries, enabling unauthorized file-write operations that should be denied by safeBins checks.
