Vulnerability details
The vulnerability allows a remote user to execute arbitrary SQL commands.
The vulnerability exists due to improper neutralization of special elements used in an SQL command in src/ListEvents.php when processing the WhichType POST parameter while filtering events by type. A remote user can send a specially crafted POST request to execute arbitrary SQL commands.
The WhichType parameter is processed without enforcing an integer type before being concatenated into multiple SQL queries, and time-based blind SQL injection is possible.
