CVE-2024-53807Network attack vector

Database disclosure via unescaped orderby parameter

Published Dec 6, 2024 · Updated May 12, 2026

SQL injection in Brandt OSS WP Mailster 1.8.16.0 and earlier allows remote authenticated users to extract database data via orderby. The plugin insufficiently escapes the user-supplied orderby parameter and incorporates it into an inadequately prepared SQL query, allowing appended SQL. Contributor-level access or higher is required, and blind query manipulation can disclose sensitive database information.
