Summary
OpenClaw's exec allowlist wrapper analysis did not unwrap env/shell dispatch chains
Details

Summary

system.run exec allowlist analysis treated wrapper binaries as the effective executable and did not fully unwrap env/shell-dispatch wrappers.

This allowed wrapper-smuggled payloads (for example env bash -lc ...) to satisfy an allowlist entry for the wrapper while executing non-allowlisted commands.

Impact

On affected versions, an actor who can trigger system.run requests under an allowlist policy could bypass intended allowlist restrictions by routing execution through wrapper binaries.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.21-2
  • Patched in next release: 2026.2.22 (pre-set below so publish can happen immediately after npm release)

Fix Commit(s)

  • 2b63592be57782c8946e521bc81286933f0f99c7

Release Process Note

patched_versions is pre-set to the planned next release (>= 2026.2.22).

After npm 2026.2.22 is published, this advisory can be published directly without further metadata edits.

OpenClaw thanks @tdjackey for reporting.
