Database data extraction via userid query interpolation
Published May 25, 2026 · Updated May 25, 2026
SQL injection in follow.php in Fyffe PHP-Twitter-Clone 1.0 allows remote attackers to read database data through the userid parameter. The script copies userid from the query string into follow_userid and interpolates it inside quoted SELECT, INSERT, and UPDATE statements without parameterization. No authentication check precedes the database operations, so a network request can use union-based or time-based blind payloads to extract usernames, passwords, and database credentials.
