Environment Variable Injection in OpenClaw system.run Enables Command Bypass

Publication date: 2026-03-19

Last updated on: 2026-03-23

Assigner: VulnCheck

Description
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.

Executive Summary

OpenClaw versions prior to 2026.2.22 have a vulnerability in the system.run function where attackers can inject environment variables. This allows them to bypass command allowlist restrictions by exploiting the SHELLOPTS and PS4 environment variables. Essentially, if an attacker can invoke system.run with environment variables scoped to a request, they can execute arbitrary shell commands outside the intended allowed commands by leveraging bash's xtrace expansion feature.

Impact Analysis

This vulnerability can allow an attacker with the ability to invoke system.run to execute arbitrary shell commands beyond the intended restrictions. This can lead to unauthorized command execution, potentially compromising the confidentiality, integrity, and availability of the affected system.
