OpenClaw < 2026.2.22 - Remote Code Execution via Shell Startup Environment Variable Injection in system.run

7.7 HighFix available

OpenClaw versions prior to 2026.2.22 fail to sanitize shell startup environment variables HOME and ZDOTDIR in the system.run function, allowing attackers to bypass command allowlist protections. Remote attackers can inject malicious startup files such as .bash_profile or .zshenv to achieve arbitrary code execution before allowlist-evaluated commands are executed.

OpenClaw's shell startup env injection bypasses system.run allowlist intent (RCE class)

Summary

system.run environment sanitization allowed shell-startup env overrides (HOME, ZDOTDIR) that can execute attacker-controlled startup files before allowlist-evaluated command bodies.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.21-2 (latest published vulnerable version)
  • Planned patched version: >= 2026.2.22

Technical Details

In affected versions:

  • Env sanitization blocked many dangerous keys, but not startup-sensitive override keys (HOME, ZDOTDIR) in host exec env paths.
  • Shell-wrapper analysis for allowlist mode models command bodies, but not shell startup side effects.
  • Runtime execution used sanitized env, so attacker-provided startup-key overrides could run hidden startup payloads first.

Observed exploit vectors:

  • HOME + bash -lc + malicious .bash_profile
  • ZDOTDIR + zsh -c + malicious .zshenv

Fix Commit(s)

  • c2c7114ed39a547ab6276e1e933029b9530ee906

Release Process Note

patched_versions is pre-set to the planned next release (>= 2026.2.22). After the npm release is published, this advisory can be published directly.

OpenClaw thanks @tdjackey for reporting.
