La firma HMAC para las sesiones de DataHub Frontend se firmaba utilizando un HMAC SHA-1 con la clave secreta de frontend.

DataHub Frontend estaba utilizando Play LegacyCookiesModule con configuraci\u00f3n predeterminada que utiliza SHA1 HMAC para firmar.

Un atacante autenticado (o un atacante que de otro modo haya obtenido un token de sesi\u00f3n) podr\u00eda descifrar la clave de firma de DataHub y obtener privilegios escalados generando una cookie de sesi\u00f3n privilegiada. Debido a que la longitud de la clave es parte del riesgo, las implementaciones deben actualizarse al gr\u00e1fico de tim\u00f3n m\u00e1s reciente y rotar su secreto de firma de sesi\u00f3n.
