Omnispace Agora Project before 26.10.0 contains a SQL injection vulnerability in the calendar functionality that allows attackers to inject malicious SQL by manipulating the sortEvents parameter, which is concatenated into the ORDER BY clause without sanitization in app/ModCalendar/CtrlCalendar.php. Attackers can exploit this flaw using error-based techniques such as extractvalue payloads to extract database information, including version data, from the underlying system.
