Summary

Gophish through 0.12.1 contains a timing discrepancy in AdminServer.Login that lets unauthenticated remote attackers enumerate valid usernames. Attackers submit candidate usernames to POST /login and measure response times, since existing accounts trigger a bcrypt comparison delay. The flaw is an observable timing discrepancy (CWE-208), and an exploit proof of concept is linked in the references.
