CVE-2026-107271— Gophish through 0.12.1 Login Rate Limit Bypass via X-Forwarded-For Spoofing

Quick assessment

Affected
gophish gophish
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Gophish 0.12.1 及更早版本存在一个速率限制绕过漏洞，允许未经身份验证的攻击者通过伪造 X-Forwarded-For 或 X-Real-IP 请求头来绕过 /login 接口的速率限制。攻击者可在每个请求中使用不同的转发地址，使得基于重写后的 RemoteAddr 进行限流的机制无法生效，从而导致攻击者可以无限尝试猜测密码或进行凭证填充（credential stuffing）攻击。

Vulnerability Title
Gophish through 0.12.1 Login Rate Limit Bypass via X-Forwarded-For Spoofing
Source: CVE Program / CVE List V5
Vulnerability Description
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.
