djangoSIGE through version 1.10 contains a user enumeration vulnerability in the ForgotPasswordView component. This flaw allows unauthenticated attackers to identify valid user accounts by exploiting differences in error messages returned by the password reset endpoint. Attackers can submit arbitrary usernames or email addresses to the POST login/esqueceu/ endpoint and determine which accounts exist based on the application's responses.
