Description

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.

Affected products

• OpenClaw: before 2026.2.19 — fixed in 2026.2.19

How to fix

Upgrade to a fixed version: OpenClaw 2026.2.19. Check the vendor advisory for mitigations.
