CVE-2026-58473

Cognee before 1.2.0 contains an improper access control vulnerability that allows unauthenticated attackers to overwrite the global LLM provider configuration by self-registering an account and calling the settings endpoint, which performs no admin or superuser check. Attackers can redirect all LLM operations instance-wide to an attacker-controlled endpoint by exploiting the process-wide singleton configuration cache, enabling exfiltration of prompts, uploaded documents, extracted entities, and knowledge graph content from all users.

Summary		(es) Cognee anterior a la versión 1.2.0 contiene una vulnerabilidad de control de acceso inadecuado que permite a atacantes no autenticados sobrescribir la configuración global del proveedor de LLM al auto-registrarse una cuenta y llamar al endpoint de configuración, que no realiza ninguna verificación de administrador o superusuario. Los atacantes pueden redirigir todas las operaciones de LLM a nivel de instancia a un endpoint controlado por el atacante al explotar la caché de configuración singleton a nivel de proceso, lo que permite la exfiltración de prompts, documentos cargados, entidades extraídas y contenido del grafo de conocimiento de todos los usuarios.
