Detailsinfo

A vulnerability, which was classified as problematic, has been found in OpenClaw up to 2026.2.21. Affected by this issue is an unknown code of the component Environment Variable Handler. The manipulation of the argument SHELLOPTS/PS4 with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.
