The Front End Users WordPress plugin through 3.2.32 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin.
The Front End Users plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's forgot-password shortcode in all versions up to, and including, 3.2.30 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Front End Users plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'user-search' shortcode in all versions up to, and including, 3.2.28 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Front End Users plugin for WordPress is vulnerable to time-based SQL Injection via the ‘order’ parameter in all versions up to, and including, 3.2.28 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.
