| Title | ningzichun student-management-system 98760f5711cf6dc8b4adca53a9e207ca49b02ebf Cross-Site Request Forgery |
|---|
| Description | The affected component is `user/delCourse.php`. It reads the authenticated student from the PHP session at lines 3-4, accepts `cid` from `$_GET['cid']` at line 5, and deletes the pending course selection at line 6. This state-changing operation is reachable through GET and has no CSRF token, Origin or Referer validation, or user confirmation. A malicious site can navigate an authenticated student to the endpoint and remove a pending course without the student's intent. |
