2DescriptionCVE.org
The Fullscreen Galleria plugin for WordPress is vulnerable to generic SQL Injection via 'href' Attribute in Post Content in all versions up to, and including, 1.6.12 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Multiple vulnerable sinks in galleria-fs.php (lines 68, 74, 146, 1074, 1078) were identified and disclosed by Wordfence; upstream fix commits have been published to the WordPress plugin repository. …
