Duplicate Advisory: Exec allowlist wrapper analysis did not unwrap env/shell dispatch chains
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-jj82-76v6-933r. This link is maintained to preserve external references.

Original Description

OpenClaw versions prior to 2026.2.22 contain an allowlist bypass vulnerability in system.run exec analysis that fails to unwrap env and shell-dispatch wrapper chains. Attackers can route execution through wrapper binaries like env bash to smuggle payloads that satisfy allowlist entries while executing non-allowlisted commands.

Severity ?
