CVE-2026-107272

Status: DeferredLow (2.3)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
