CVE-2026-107272
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.
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
Description
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.
