Executive brief
The WP Review Slider Pro plugin for WordPress, which is used to display customer reviews from various social platforms, contains a security flaw that allows users with basic account access to interfere with the site's database. By exploiting this vulnerability, an attacker could potentially steal sensitive information or access data they are not authorized to see. This could lead to a breach of customer data or compromise the integrity of the website's operations.
Technical details
The WP Review Slider Pro plugin for WordPress is vulnerable to SQL Injection due to insufficient input validation and lack of prepared statements in the wpfb_find_reviews AJAX action. Specifically, the handler reads the 'curselrevs' POST parameter raw without sanitization or type casting, then concatenates array elements directly into a SQL 'WHERE id IN' clause. An authenticated attacker with Subscriber-level permissions or higher can exploit this to append malicious SQL queries and extract sensitive data from the database. The vulnerability exists in all versions up to and including 12.6.8.
