ProQuiz contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the my_account.php script not properly sanitizing user-supplied input to the 'instid' parameter. This may allow an attacker to inject or manipulate SQL queries in the back-end database, allowing for the manipulation or disclosure of arbitrary data. Additionally, if a failed query is performed, the program will render the user's input without sanitizing it. This causes the resulting error message to potentially be used as a cross-site scripting (XSS) vector.
