What is CVE-2026-41358?

The vulnerable version of OpenClaw, prior to 2026.4.2, fails to adequately filter Slack thread context based on a sender allowlist. This oversight permits attackers to exploit the system by injecting unauthorized thread messages through replies from allowlisted users, effectively circumventing sender access controls. As a result, malicious actors can manipulate the model context, posing significant risks to security and data integrity.
