Description

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.
