Description
WordPress Plugin Quiz and Survey Master (QSM)-Easy Quiz and Survey Maker is prone to multiple SQL injection vulnerabilities because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. Exploiting these issues could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. WordPress Plugin Quiz and Survey Master (QSM)-Easy Quiz and Survey Maker version 4.4.2 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 4.4.3 or latest
