Name of the Vulnerable Software and Affected Versions Mattermost versions prior to 7.8.10 Mattermost versions prior to 8.1.1

Description The issue arises from the failure to properly verify permissions needed for viewing archived public channels. This allows a member of one team to obtain details about the archived public channels of another team via the "GET /api/v4/teams//channels/deleted" endpoint.

Recommendations For versions prior to 7.8.10, update to version 7.8.10 or later. For versions prior to 8.1.1, update to version 8.1.1 or later. As a temporary workaround, consider restricting access to the "GET /api/v4/teams//channels/deleted" endpoint until a patch is available.
