Reflected XSS in Code Projects Assessment Management 1.0 allows remote authenticated users to run script in a victim's browser. The mark value reaches an integer INSERT after only SQL escaping, and add-single-mark.php returns the resulting MySQL error without HTML encoding. Exploitation requires lecturer-level access and victim interaction; the script executes within the application's origin.
