CVE-2026-46372
SillyTavern: SSRF in SearXNG Search Proxy via Unvalidated baseUrl
Description
SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to 1.18.0, SillyTavern exposes /api/search/searxng, which accepts attacker-controlled baseUrl and uses it directly to build outbound server-side fetches. An authenticated low-privilege user can point baseUrl at an internal or loopback HTTP service and receive the /search response body. This vulnerability is fixed in 1.18.0.

Action Type Old Value New Value Added Translation Title: SillyTavern, Description: SillyTavern es una interfaz de usuario instalada localmente que permite a los usuarios interactuar con modelos de lenguaje grandes de generación de texto, motores de generación de imágenes y modelos de voz de texto a voz. Antes de la 1.18.0, SillyTavern expone /api/search/searxng, que acepta un baseUrl controlado por el atacante y lo usa directamente para construir recuperaciones salientes del lado del servidor. Un usuario autenticado de bajo privilegio puede apuntar baseUrl a un servicio HTTP interno o de bucle invertido y recibir el cuerpo de la respuesta de /search. Esta vulnerabilidad está corregida en la 1.18.0. -
