Technical Analysis

CVE-2026-100575 is a missing authorization vulnerability in OpenClaw Slack affecting versions prior to 2026.8.1. The issue arises from improper enforcement of sender allowlists in multi-person direct messages, enabling unauthorized participants to trigger Slack agents and access associated tools and data by circumventing configured sender policies.

Potential Impact

Unauthorized participants in multi-person direct messages can bypass sender allowlists and trigger Slack agents, potentially accessing sensitive tools and data granted to those agents. This could lead to unauthorized data exposure or misuse of Slack agent capabilities.

Mitigation Recommendations

Upgrade OpenClaw Slack to version 2026.8.1 or later, where this authorization issue has been fixed. No other mitigation guidance is provided; applying the official fix is recommended.
