Descriptions

Mattermost fails to properly sanitize the request to /api/v4/redirect_location allowing an attacker, sending a specially crafted request to /api/v4/redirect_location, to fill up the memory due to caching large items.

Mattermost no puede sanitizar adecuadamente la solicitud a /api/v4/redirect_location, lo que permite que un atacante envíe una solicitud especialmente manipulada a /api/v4/redirect_location para llenar la memoria debido al almacenamiento en caché de elementos grandes.
