Name of the Vulnerable Software and Affected Versions Mattermost versions prior to 8.1.9
Description Mattermost fails to check if compliance export is enabled when fetching posts of public channels, allowing a user that is not a member of the public channel to fetch the posts, which will not be audited in the compliance export.
Recommendations For versions prior to 8.1.9, update to version 8.1.9 or later to resolve the issue. As a temporary workaround, consider restricting access to public channels to minimize the risk of unauthorized post fetching.
