CVE-2026-27566: OpenClaw's exec allowlist wrapper analysis did not unwrap env/shell dispatch chains

highCVSS 4.0 7.1GHSA-jj82-76v6-933r

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.

Advisory details

From the GitHub Advisory Database (CC BY 4.0).

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.
