Name of the Vulnerable Software and Affected Versions Joomla! versions 4.2.0 through 4.3.1

Description The issue is related to the lack of rate limiting, which allows brute force attacks against Multi-Factor Authentication (MFA) methods. MFA is a security process that requires a user to provide two or more authentication factors to access a system, application, or network. The absence of rate limiting enables attackers to attempt multiple login attempts without restriction, potentially leading to unauthorized access.

Recommendations For Joomla! versions 4.2.0 through 4.3.1, consider implementing rate limiting on MFA methods to prevent brute force attacks until a patch is available. As a temporary workaround, restrict access to MFA-protected areas of the application to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
