CVE-2026-6448
MediumCVSS 4.9Summary
The Quiz and Survey Master (QSM) plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'order' parameter in all versions up to and including 11.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
Risk Assessment
Authenticated attackers with admin-level access can append additional SQL queries into existing queries, allowing them to extract sensitive information from the database. If the secret key is exposed, this can be exploited by lower-privileged users.
Recommendation
It is recommended to update the plugin to the latest version to mitigate this vulnerability. Additionally, monitoring database access and implementing appropriate security measures is advised.
Original NVD description (English source)
The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'order' parameter in all versions up to, and including, 11.1.2 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 admin-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. If the secret key is exposed, this can be exploited by lower-privileged users.
