Name of the Vulnerable Software and Affected Versions Quiz and Survey Master (QSM) WordPress plugin versions prior to 11.1.3

Description The front-end credential-check functionality lacks rate limiting and standard failed-login auditing. Because the system returns distinct responses for valid and invalid accounts, unauthenticated attackers can enumerate valid usernames and perform brute-force password attacks while bypassing existing brute-force protections.

Recommendations Update the Quiz and Survey Master (QSM) WordPress plugin to version 11.1.3 or later.
