CVE-2026-56261

Crawl4AI before 0.8.7 contains a server-side request forgery (SSRF) vulnerability in the Docker API server's /crawl/job and /llm/job endpoints, which accept webhook URLs without destination validation. An attacker can supply webhook URLs pointing to private or internal IP ranges, Docker networks, or cloud metadata endpoints (e.g. 169.254.169.254), causing the server to make requests to internal services and potentially expose cloud metadata.

Summary		(es) Crawl4AI anterior a la versión 0.8.7 contiene una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en los puntos finales /crawl/job y /llm/job del servidor API de Docker, que aceptan URL de webhook sin validación de destino. Un atacante puede proporcionar URL de webhook que apuntan a rangos de IP privados o internos, redes de Docker, o puntos finales de metadatos de la nube (por ejemplo, 169.254.169.254), haciendo que el servidor realice peticiones a servicios internos y potencialmente exponga metadatos de la nube.
