Authenticated database disclosure via unsanitized id parameter
Published Jul 1, 2026 · Updated Jul 1, 2026
SQL injection in The Guardian Language System through commit e42c395 allows remote authenticated users to extract database contents. The subtitles.php handler concatenates the id GET parameter inside a quoted SELECT statement and passes the resulting string to mysqli_query without sanitization. Access to the endpoint requires an application login, after which crafted id values expose database contents through SQL error responses.
