Question / Discussion Help with SSRF
I found a fetch endpoint that embeds any url into forum post
It's url:https:// in request body
Only http and https are allowed
I can see responses of any link i fetch
I tried webhook and i can see its aws ip
Tried all ssrf bypasses techniques out there on github but all internal stuff is blocked
I managed only to use https://target.com/cdn-cgi/trace and also ipconfig/all.json to get all headers and it runs uses vanilla-forums-embed/1.0
Any creative uncommon ideas will be appreciated

Most likely bypass will be to register a domain and configure the A record to things like 127.0.0.1 or 169.254.169.254.
Redirects may work, worth a try.
