## Technical details

A timing discrepancy vulnerability in the /auth/check endpoint allows observable differences in response time based on whether an account exists. Existing accounts trigger two bcrypt operations while non-existent accounts trigger one, enabling unauthenticated attackers to enumerate valid usernames and email addresses through timing analysis. No authentication is required to exploit this vulnerability.
