Summary Duplicate Advisory: OpenClaw's ACP child sessions inherit subagent security envelope constraints ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-q3jj-46pq-826r. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.4.22 contains a security envelope constraint bypass vulnerability allowing restricted subagents to spawn ACP child sessions that fail to inherit depth, child-count limits, control scope, or target-agent restrictions. Attackers can exploit this by spawning child sessions that bypass subagent-only constraints, potentially escalating privileges or accessing restricted resources.
