Authenticated database disclosure via unsanitized post_id query
Published Mar 23, 2026 · Updated Mar 23, 2026
SQL injection in SourceCodester Simple E-Learning System 1.0 allows remote authenticated users to read database data via the post_id GET parameter. The delete_post.php handler inserts the unsanitized GET value into a MySQL query, enabling time-based blind inference with SLEEP expressions. A valid application session is required, and successful exploitation discloses database contents byte by byte without direct query output.
