Auth0-PHP is a PHP SDK for Auth0 Authentication and Management APIs. From version 8.0.0 to before version 8.19.0, in applications built with the Auth0 PHP SDK, cookies are encrypted with insufficient entropy, which may result in threat actors brute-forcing the encryption key and forging session cookies. This issue has been patched in version 8.19.0.

Summary		(es) Auth0-PHP es un SDK de PHP para las API de autenticación y gestión de Auth0. Desde la versión 8.0.0 hasta antes de la versión 8.19.0, en aplicaciones construidas con el SDK de PHP de Auth0, las cookies se cifran con entropía insuficiente, lo que puede resultar en que actores de amenazas fuercen la clave de cifrado por fuerza bruta y falsifiquen cookies de sesión. Este problema ha sido parcheado en la versión 8.19.0.
