Descriptions

The Contest Gallery WordPress plugin before 19.1.5.1, Contest Gallery Pro WordPress plugin before 19.1.5.1 do not escape the user_id POST parameter before concatenating it to an SQL query in ajax-functions-backend.php. This may allow malicious users with at least author privilege to leak sensitive information from the site's database.

El complemento Contest Gallery de WordPress anterior a 19.1.5.1 y el complemento Contest Gallery Pro de WordPress anterior a 19.1.5.1 no escapan del parámetro POST user_id antes de concatenarlo a una consulta SQL en ajax-functions-backend.php. Esto puede permitir que usuarios malintencionados con al menos privilegios de autor filtren información confidencial de la base de datos del sitio.

The Contest Gallery plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 19.1.5 due to insufficient escaping on the user supplied user_id parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database
