Detailsinfo

A vulnerability classified as problematic has been found in Gophish up to 0.12.1. Affected is an unknown code of the component Rate Limiting. The manipulation of the argument X-Forwarded-For/X-Real-IP with an unknown input leads to a excessive authentication vulnerability. CWE is classifying the issue as CWE-307. The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is available at blog.ostorlab.co. This vulnerability is traded as CVE-2026-107271 since 10/07/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1110.001 by the MITRE ATT&CK project.
