Description
Mailpit is an email testing tool and API for developers. Versions 1.28.0 and below have a Server-Side Request Forgery (SSRF) vulnerability in the /proxy endpoint, allowing attackers to make requests to internal network resources.

This vulnerability is limited to HTTP GET requests with minimal headers. The issue is fixed in version 1.28.1.
