stoatchat versions before 0.15.5 contain a denial of service vulnerability in the acknowledgement worker that processes mass mention messages. (CVE-2026-100675)
Stoatchat versions before 0.15.5 have a denial of service vulnerability in the acknowledgement worker that handles mass mention messages. Authenticated users can exploit this by sending five crafted role-mention messages, causing all acknowledgement workers to terminate. This disables push notifications and mention badges across the deployment until the API process is restarted.
AI Analysis
Technical Summary
CVE-2026-100675 describes a denial of service vulnerability in stoatchat versions prior to 0.15.5.
