Executive brief
ProfileGrid is a WordPress plugin used to manage user profiles, groups, and online communities. A security flaw in this plugin allows logged-in users, even those with low-level 'Subscriber' permissions, to perform unauthorized database queries. This could lead to the theft of sensitive information stored in the website's database, potentially compromising user data and site security.
Technical details
A blind SQL injection vulnerability exists in the ProfileGrid plugin for WordPress due to insufficient escaping of the 'rid' parameter and a lack of proper SQL query preparation. The flaw is located within the database handling logic across several files, including class-profile-magic-dbhandler.php and class-profile-magic-request.php. An authenticated attacker with at least Subscriber-level privileges can exploit this by sending crafted network requests to append malicious SQL commands to existing queries. Successful exploitation allows for the extraction of sensitive data from the WordPress database via inference (blind SQLi). The issue is addressed in versions following 5.9.8.4.
