Name of the Vulnerable Software and Affected Versions Mattermost versions 9.7.x through 9.7.5 Mattermost versions 9.8.x through 9.8.2 Mattermost versions 9.9.x through 9.9.2

Description The issue arises from the failure to properly propagate permission scheme updates across cluster nodes. This allows a user to retain old permissions even after the permission scheme has been updated.

Recommendations For versions 9.7.x through 9.7.5, update to a version later than 9.7.5 to resolve the issue. For versions 9.8.x through 9.8.2, update to a version later than 9.8.2 to resolve the issue. For versions 9.9.x through 9.9.2, update to a version later than 9.9.2 to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources until the update is applied.
