Description
The vulnerability allows a remote attacker to disclose sensitive information about registered users.
The vulnerability exists due to observable response discrepancy in the code-based login and password reset forms when processing authentication challenge requests. A remote attacker can submit email addresses and observe differing error behavior to disclose sensitive information about registered users.
This only affects installations using the code or password-reset authentication method, and exploitation is only possible if an error occurs during challenge creation or within the user.login:failed hook.
