Vulnerability from github – Published: 2026-03-03 21:48 – Updated: 2026-03-30 13:47

Summary

OpenClaw exec allowlist safeBins short-option bypass could permit arbitrary file write

Details

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.

CVE-2026-32017 (GCVE-0-2026-32017)

Vulnerability from cvelistv5 – Published: 2026-03-19 22:06 – Updated: 2026-03-25 14:27 X_Open Source

Title

OpenClaw < 2026.2.19 - Arbitrary File Write via Short-Option Bypass in exec Allowlist

Summary

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.
