Recommendation: Monitor — no exploitation signal at the moment.

OpenClaw versions prior to 2026.3.7 contain a sandbox escape vulnerability in the /acp spawn command that allows authorized sandboxed sessions to initialize host-side ACP runtime. Attackers can bypass sandbox restrictions by invoking the /acp spawn slash-command to cross from sandboxed chat context into host-side ACP session initialization when ACP is enabled.
