djangoSIGE through 1.10 (commit a6fe7e8) contains a user enumeration vulnerability in ForgotPasswordView within djangosige/apps/login/views.py that allows unauthenticated attackers to identify valid accounts by observing distinct error messages returned by the password reset endpoint. Attackers can submit arbitrary usernames or email addresses to the POST login/esqueceu/ endpoint and distinguish between existing and non-existing accounts based on observable discrepancies in the application's responses.
