      "value": "Docling-Graph turns documents into validated Pydantic objects, then builds a directed knowledge graph with explicit semantic relationships. Prior to 1.5.1, the URLInputHandler class in docling_graph/core/input/handlers.py makes HTTP requests to user-supplied URLs without validating whether the target resolves to a private, loopback, or link-local IP address. The URLValidator only checks for a valid scheme and non-empty netloc, performing no IP-level validation. Additionally, requests.head() was called with allow_redirects=True, allowing an attacker to redirect requests to internal endpoints via an intermediary URL. An attacker who can control the --source CLI argument or PipelineConfig.source API parameter can trigger Server-Side Request Forgery (SSRF). This vulnerability is fixed in 1.5.1."

      "value": "Docling-Graph convierte documentos en objetos Pydantic validados, luego construye un grafo de conocimiento dirigido con relaciones semánticas explícitas. Antes de la versión 1.5.1, la clase URLInputHandler en docling_graph/core/input/handlers.py realiza peticiones HTTP a URLs proporcionadas por el usuario sin validar si el objetivo se resuelve en una dirección IP privada, de bucle invertido o de enlace local. El URLValidator solo comprueba un esquema válido y un netloc no vacío, sin realizar ninguna validación a nivel de IP. Además, requests.head() se llamaba con allow_redirects=True, permitiendo a un atacante redirigir peticiones a puntos finales internos a través de una URL intermediaria. Un atacante que puede controlar el argumento CLI --source o el parámetro API PipelineConfig.source puede desencadenar una Falsificación de Petición del Lado del Servidor (SSRF). Esta vulnerabilidad se corrige en la versión 1.5.1."
