Descriptions

In MediaWiki before 1.31.8, 1.32.x and 1.33.x before 1.33.4, and 1.34.x before 1.34.2, private wikis behind a caching server using the img_auth.php image authorization security feature may have had their files cached publicly, so any unauthorized user could view them. This occurs because Cache-Control and Vary headers were mishandled.

En MediaWiki en versiones anteriores a la 1.31.8, 1.32.x y 1.33.x versiones anteriores a la 1.33.4, y 1.34.x en versiones anteriores a la 1.34.2, los wikis privados que se encuentran detrás de un servidor de almacenamiento en caché que utiliza la función de seguridad de autorización de imágenes img_auth.php pueden haber tenido sus archivos almacenados en caché públicamente, de modo que cualquier usuario no autorizado pueda verlos. Esto ocurre porque el control de la caché y las cabeceras de Vary se manejaron mal
