An Open Redirect vulnerability was discovered in the SAML Single Sign-On functionality due to insufficient validation of a user-controlled redirection parameter. An unauthenticated attacker can craft a request to the SAML sign-in endpoint and poison the cached SAML redirection for other users who subsequently initiate SAML Single Sign-On, enabling phishing and credential-theft attacks, as well as disrupting SAML authentication for all affected users.
