Descriptions

Mattermost fails to enforce a limit for the size of the cache entry for OpenGraph data allowing an attacker to send a specially crafted request to the /api/v4/opengraph filling the cache and turning the server unavailable.

Mattermost no aplica un límite para el tamaño de la entrada de caché para los datos de OpenGraph, lo que permite a un atacante enviar una solicitud especialmente manipulada al /api/v4/opengraph, llenando el caché y haciendo que el servidor no esté disponible.
