Descriptions
Mattermost fails to use innerText / textContent when setting the channel name in the webapp during autocomplete, allowing an attacker to inject HTML to a victim's page by create a channel name that is valid HTML. No XSS is possible though.
Mattermost no utiliza el texto interno/textContent al configurar el nombre del canal en la aplicación web durante el autocompletado, lo que permite a un atacante inyectar HTML en la página de una víctima creando un nombre de canal que sea HTML válido. Sin embargo, no es posible XSS.
