Authenticated arbitrary SQL via calendar userId injection
Published Aug 17, 2026 · Updated Aug 18, 2026
Time-based SQL injection in Brainformatik CRM+ 2025.6 and earlier allows remote authenticated users to execute arbitrary SQL via a calendar request. The CheckConflictOfDates action passes the POST userId value into a MySQL query without neutralizing SQL syntax, so a SLEEP subquery changes response timing. A valid CRM+ login and access to appointment creation are required; successful exploitation exposes database contents and operations, while code execution is reported but its path is undisclosed.
