CVE-2021-38314

The Gutenberg Template Library & Redux Framework plugin <= 4.2.11 for WordPress registered several AJAX actions available to unauthenticated users in the `includes` function in `redux-core/class-redux-core.php` that were unique to a given site but deterministic and predictable given that they were based on an md5 hash of the site URL with a known salt value of '-redux' and an md5 hash of the previous hash with a known salt value of '-support'. These AJAX actions could be used to retrieve a list of active plugins and their versions, the site's PHP version, and an unsalted md5 hash of site’s `AUTH_KEY` concatenated with the `SECURE_AUTH_KEY`.

El plugin Gutenberg Template Library &amp; Redux Framework versiones anteriores a 4.2.11 incluyéndola para WordPress, registraba varias acciones AJAX disponibles para usuarios no autenticados en la función "includes" en el archivo "redux-core/class-redux-core.php" que eran únicas para un sitio determinado pero deterministas y predecibles dado que se basaban en un hash md5 de la URL del sitio con un valor de salt conocido de "-redux" y un hash md5 del hash anterior con un valor de salt conocido de "-support". Estas acciones AJAX podrían ser usadas para recuperar una lista de plugins activos y sus versiones, la versión PHP del sitio, y un hash md5 sin salt de la "AUTH_KEY" del sitio concatenada con la "SECURE_AUTH_KEY"
