The vulnerability is triggered by manipulating the User argument, which allows for unauthorized SQL command execution. This vulnerability can be exploited remotely, and a public exploit is available.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, or in some cases, executing administrative operations on the database.
