Last modified
CVE-2026-15963 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to generic SQL Injection via 'randon_category' Quiz Option in all versions up to, and including, 11.2.1 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 custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
