Exposure of Resource to Wrong Sphere
When running in a High Availability configuration, Mattermost fails to sanitize some of the "user_updated" and "post_deleted" events broadcast to all users, leading to disclosure of sensitive information to some of the users with currently connected Websocket clients. This issue affects github.com/mattermost/mattermost-server versions through 7.1.5 and 7.2.0 through 7.7.1.
CWE-668 - Exposure of Resource to Wrong Sphere
