      "value": "mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9.4, the 3rd-party init SSO functionality of mod_auth_openidc was reported to be vulnerable to an open redirect attack by supplying a crafted URL in the `target_link_uri` parameter. A patch in version 2.4.9.4 made it so that the `OIDCRedirectURLsAllowed` setting must be applied to the `target_link_uri` parameter. There are no known workarounds aside from upgrading to a patched version."

En las versiones anteriores a 2.4.9.4, la funcionalidad de SSO init de terceros de mod_auth_openidc era vulnerable a un ataque de redirecci\u00f3n abierta mediante el suministro de una URL dise\u00f1ada en el par\u00e1metro \"target_link_uri\". Un parche en la versi\u00f3n 2.4.9.4 hizo que la configuraci\u00f3n \"OIDCRedirectURLsAllowed\" se aplicara al par\u00e1metro \"target_link_uri\". No se conocen soluciones aparte de la actualizaci\u00f3n a una versi\u00f3n parcheada"
