Recommendation: Monitor — no exploitation signal at the moment.

OpenClaw before 2026.4.2 fails to filter Slack thread context by sender allowlist, allowing non-allowlisted messages to enter agent context. Attackers can inject unauthorized thread messages through allowlisted user replies to bypass sender access controls and manipulate model context.
