An issue was discovered in Joomla! 4.2.0 through 4.3.1. The lack of rate limiting allowed brute force attacks against MFA methods.
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.
