CVE-2026-35486

Full vulnerability record from the local CVENow database.

Description

text-generation-webui is an open-source web interface for running Large Language Models. Prior to 4.3, he superbooga and superboogav2 RAG extensions fetch user-supplied URLs via requests.get() with zero validation — no scheme check, no IP filtering, no hostname allowlist. An attacker can access cloud metadata endpoints, steal IAM credentials, and probe internal services. The fetched content is exfiltrated through the RAG pipeline. This vulnerability is fixed in 4.3.

Antes de la versión 4.3, las extensiones RAG superbooga y superboogav2 recuperan URLs proporcionadas por el usuario a través de requests.get() sin ninguna validación - sin verificación de esquema, sin filtrado de IP, sin lista blanca de nombres de host. Un atacante puede acceder a puntos finales de metadatos en la nube, robar credenciales de IAM y sondear servicios internos. El contenido recuperado es exfiltrado a través del pipeline RAG. Esta vulnerabilidad está corregida en la versión 4.3."
