DescriptionCVE.org

The WPML Multilingual CMS plugin for WordPress is vulnerable to SQL Injection via the 'sorting' parameter in all versions up to, and including, 4.9.5 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 translator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

AnalysisAI

SQL Injection in WPML Multilingual CMS for WordPress allows authenticated attackers holding translator-level access or above to extract sensitive information from the underlying database on all plugin versions through 4.9.5. The vulnerable code resides in the Translation Manager REST API's job-ordering logic - specifically the unsanitized 'sorting' parameter processed by OrderQueryHelper - where user-supplied input is appended to existing SQL queries without adequate escaping or prepared-statement protections. …
