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. ### Fix Commit(s) - cfe8457a0f4aae5324daec261d3b0aad1461a4bc - bafdbb6f112409a65decd3d4e7350fbd637c7754 - fec48a5006eab37c6a5821726ccaeec886486b13 OpenClaw thanks @FailButWin and @Redgrave961 for reporting.
