Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs."}, {"lang": "es", "value": "Angular es una plataforma de desarrollo para construir aplicaciones web m\u00f3viles y de escritorio usando TypeScript/JavaScript y otros lenguajes. Versiones anteriores a las 19.2.16, 20.3.14 y 21.0.1, existe una fuga de token XSRF a trav\u00e9s de URLs relativas al protocolo en clientes HTTP de Angular. La vulnerabilidad es una fuga de credenciales por l\u00f3gica de aplicaci\u00f3n que conduce a la divulgaci\u00f3n no autorizada del token de Cross-Site Request Forgery (XSRF) a un dominio controlado por el atacante. El HttpClient de Angular tiene un mecanismo de protecci\u00f3n XSRF incorporado que funciona comprobando si una URL de petici\u00f3n comienza con un protocolo (http:// o https://) para determinar si es de origen cruzado. Si la URL comienza con una URL relativa al protocolo (//), se trata incorrectamente como una petici\u00f3n del mismo origen, y el token XSRF se a\u00f1ade autom\u00e1ticamente a la cabecera X-XSRF-TOKEN. Este problema ha sido parcheado en las versiones 19.2.16, 20.3.14 y 21.0.1. Una soluci\u00f3n alternativa para este problema implica evitar el uso de URLs relativas al protocolo (URLs que comienzan con //) en las peticiones de HttpClient. Todas las URLs de comunicaci\u00f3n de backend deben ser codificadas de forma r\u00edgida como rutas relativas (que comienzan con una sola /) o URLs absolutas de confianza y completamente calificadas."}], "lastModified": "2026-10-19T13:10:00.110", "sourceIdentifier": "security-advisories@github.com"}
