CVE-2025-61782

OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to version 6.8.3, an open redirect vulnerability exists in the OpenCTI platform's SAML authentication endpoint (/auth/saml/callback). By manipulating the RelayState parameter, an attacker can force the server to issue a 302 redirect to any external URL, enabling phishing, credential theft, and arbitrary site redirection. This issue has been patched in version 6.8.3.

Summary		(es) OpenCTI es una plataforma de código abierto para gestionar el conocimiento y los observables de la inteligencia de ciberamenazas. Antes de la versión 6.8.3, existe una vulnerabilidad de redirección abierta en el endpoint de autenticación SAML de la plataforma OpenCTI (/auth/saml/callback). Al manipular el parámetro RelayState, un atacante puede forzar al servidor a emitir una redirección 302 a cualquier URL externa, lo que permite phishing, robo de credenciales y redirección arbitraria de sitios. Este problema ha sido parcheado en la versión 6.8.3.
