SillyTavern - Server-Side Request Forgery

SillyTavern versions up to and including 1.17.0 expose the /api/search/searxng endpoint, which accepts an attacker-controlled baseUrl parameter and uses it directly to build outbound server-side fetch requests. An authenticated low-privilege user can point baseUrl at an internal or loopback HTTP service and receive the full response body, enabling read access to internal services, cloud metadata endpoints, and private network resources.
