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.

Gophish through 0.12.1 contains an insecure direct object reference vulnerability that allows authenticated users to take over other users' groups, templates, landing pages and sending profiles. Attackers can supply another user's sequential id in POST requests to /api/groups/, /api/templates/, /api/pages/ or /api/smtp/ to overwrite and reassign objects, locking out owners and exposing victims' recipient lists.

Gophish through 0.12.1 contains a rate limit bypass vulnerability that allows unauthenticated attackers to evade /login throttling by spoofing X-Forwarded-For or X-Real-IP headers. Attackers can send a different forwarded address per request so the limiter keyed on rewritten RemoteAddr never triggers, enabling unlimited password guessing and credential stuffing.

Gophish through 0.12.1 contains stored and reflected cross-site scripting vulnerabilities that allow attackers to inject script by returning malicious SMTP server error messages. Attackers controlling or intercepting a sending profile's SMTP server can execute script when administrators view campaign results or send test emails, stealing API keys.

Gophish 0.11.0 through 0.12.1 contains a server-side request forgery vulnerability that allows authenticated low-privileged users to reach loopback and private hosts via POST /api/import/site. Attackers can submit internal URLs, which the default dialer deny list does not block, to read service responses and enumerate internal hosts and ports through error messages.
