Description The issue arises when shared channels are enabled in Mattermost, causing it to fail to redact remote users' original email addresses stored in user props. This occurs even when email addresses are otherwise configured not to be visible in the local server.
Recommendations For Mattermost versions 9.8.x through 9.8.2, update to a version later than 9.8.2 to resolve the issue. For Mattermost versions 9.5.x through 9.5.7, update to a version later than 9.5.7 to resolve the issue. For Mattermost versions 9.9.x through 9.9.1, update to a version later than 9.9.1 to resolve the issue. For Mattermost versions 9.10.x through 9.10.0, update to a version later than 9.10.0 to resolve the issue. As a temporary workaround, consider disabling shared channels until a patch is available.
