## Technical details

The WP TripAdvisor Review Slider plugin for WordPress is vulnerable to SQL Injection via the 'filtersource' parameter in versions up to and including 14.6. The root cause is insufficient escaping of user-supplied input and a lack of proper SQL query preparation using WordPress's $wpdb->prepare() or similar mechanisms. An authenticated attacker with administrator-level privileges can exploit this by appending malicious SQL queries to existing ones. This enables the extraction of sensitive data from the WordPress database. A patch appears to be available in the latest changeset (3607754).
