Vulnerability from github – Published: 2026-10-07 18:32 – Updated: 2026-10-07 18:32

Details

Gophish through 0.12.1 contains a timing discrepancy vulnerability in AdminServer.Login that allows unauthenticated attackers to enumerate valid usernames by measuring login response times. Attackers can submit candidate usernames to POST /login and detect bcrypt comparison delays for existing accounts, narrowing targets for password guessing or credential stuffing.

Severity

3.7 (Low)


                  
                    CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N
