BREW-openclaw-cli-CVE-2026-32017 — OpenClaw exec allowlist safeBins short-option bypass could permit arbitrary file write

Affected: Homebrew: openclaw-cli

### 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

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

Affected: OpenClaw

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.
