### Summary This advisory addresses a security vulnerability in Mautic related to the "Forget your password" functionality. This vulnerability could be exploited by unauthenticated users to enumerate valid usernames. User Enumeration via Timing Attack: A user enumeration vulnerability exists in the "Forget your password" functionality. Differences in response times for existing and non-existing users, combined with a lack of request limiting, allow an attacker to determine the existence of usernames through a timing-based attack. ### Mitigation Please update to a version that addresses this timing vulnerability, where password reset responses are normalized to respond at the same time regardless of user existence. ### Workarounds None If you have any questions or comments about this advisory: Email us at [email protected]
