Description

OpenClaw before 2026.4.27 contains an authorization bypass vulnerability in QQBot pre-dispatch slash commands that allows authenticated senders to skip allowFrom policy checks. Attackers can invoke slash commands before configured access control policies are applied, potentially triggering command handling from blocked senders depending on operator configuration.
