CVE-2026-32017
OpenClaw < 2026.2.19 - Arbitrary File Write via Short-Option Bypass in exec Allowlist
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.

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.
