Statamic CMS vulnerable to email enumeration via forgot password endpoint

Impact

Responses from the forgot password forms hinted at whether an account existed for a given email address. An unauthenticated attacker could use this to enumerate valid users, which can aid in follow-up credential-based attacks.

Patches

This has been fixed in 5.73.21 and 6.15.0. The forgot password forms now return the same generic response regardless of whether the submitted email matches a registered user.
