Summary
OpenClaw Node host system.run rawCommand/command mismatch can bypass allowlist/approvals
Details

Summary

A mismatch between rawCommand and command[] in the node host system.run handler could cause allowlist/approval evaluation to be performed on one command while executing a different argv.

Affected Configurations

This only impacts deployments that:

  • Use the node host / companion node execution path (system.run on a node).
  • Enable allowlist-based exec policy (security=allowlist) with approval prompting driven by allowlist misses (for example ask=on-miss).
  • Allow an attacker to invoke system.run.

Default/non-node configurations are not affected.

Impact

In affected configurations, an attacker who can invoke system.run can bypass allowlist enforcement and approval prompts by supplying an allowlisted rawCommand while providing a different command[] argv for execution.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.13
  • Patched version: >= 2026.2.14 (planned next release)

Fix

Enforce rawCommand/command[] consistency (gateway fail-fast + node host validation).

Fix Commit(s)

  • cb3290fca32593956638f161d9776266b90ab891

Release Process Note

This advisory pre-sets the patched version to the planned next release (2026.2.14). Once openclaw@2026.2.14 is published to npm, the advisory can be published without further edits.

Thanks @christos-eth for reporting.
