Administrator-only SQL injection via unprepared query

Published Dec 28, 2023 · Updated Apr 28, 2026

SQL injection in Mediaburst Clockwork SMS Notfications 3.0.4 and earlier allows remote authenticated users to read WordPress database data. An undisclosed administrator-controlled parameter is insufficiently escaped before incorporation into an existing SQL query that lacks sufficient preparation. Administrator access is required, and the published evidence establishes database disclosure but does not name the parameter, function, or query.
