Vulnerability details

The PickPlugins Question Answer plugin for WordPress is vulnerable to SQL Injection in versions up to and including 1.2.73. This is due to insufficient sanitization of user-supplied input via the 'id' GET parameter in the user profile template combined with the use of wp_unslash() which removes WordPress's magic quotes protection, followed by direct concatenation into a SQL query without proper escaping or prepared statements in the qa_user_profile_card() function. This makes it possible for unauthenticated attackers to append additional SQL queries into existing queries, which can be used to extract sensitive information from the database.
