Medium (5.4) in mattermost mattermost. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/mattermost/mattermost/server/v8 8.1.4.
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.
