OpenClaw system.run shell environment variable sanitization bypass

IdentifiersCVE-2026-32056CWE-15

CVE-2026-32056 is a remote code execution vulnerability in OpenClaw versions prior to 2026.2.22. The flaw is in the system.run function, which does not properly sanitize the shell startup environment variables HOME and ZDOTDIR before invoking shell-based command execution. Because these variables influence where shells load initialization files, an attacker can manipulate them so that malicious shell startup files are processed before the intended command is evaluated against the application’s command allowlist. This enables bypass of the allowlist protection and execution of attacker-controlled code prior to the approved command flow.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to bypass command allowlist protections and achieve arbitrary code execution in the context of the vulnerable OpenClaw process. This can lead to full compromise of the application’s execution context, unauthorized actions performed through the application, and potential access to sensitive data available to that process.

Mitigation

If you can’t patch tonight, do this now.

Until patched versions are fully deployed, reduce exposure by preventing untrusted input from influencing environment variables passed to shell execution, especially HOME and ZDOTDIR. Where operationally feasible, avoid shell-mediated execution paths in system.run, constrain or disable features that permit remote users to trigger command execution, and run the service with the least privileges necessary to limit post-exploitation impact.

Remediation

Patch, then assume compromise.

Upgrade OpenClaw to version 2026.2.22 or later, where sanitization of shell startup environment variables associated with system.run has been corrected. Apply the vendor-provided security updates across all affected deployments and verify that no vulnerable versions remain in use.
