Summary
OpenClaw < 2026.2.22 - Remote Code Execution via SHELLOPTS/PS4 Environment Injection in system.run
Original description
The description as published by the source.
OpenClaw versions prior to 2026.2.22 contain an environment variable injection vulnerability in the system.run function that allows attackers to bypass command allowlist restrictions via SHELLOPTS and PS4 environment variables. An attacker who can invoke system.run with request-scoped environment variables can execute arbitrary shell commands outside the intended allowlisted command body through bash xtrace expansion.
