The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘pm_get_messenger_notification’ function in all versions up to, and including, 5.9.5.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a logged-in user into performing an action such as clicking on a link.
The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to blind and time-based SQL Injections via the rid and search parameters in all versions up to, and including, 5.9.4.7 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 Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 5.9.4.5 via deserialization of untrusted input in the get_user_meta_fields_html function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
