CVE-2022-24804

Discourse is an open source platform for community discussion. In stable versions prior to 2.8.3 and beta versions prior

Discourse is an open source platform for community discussion. In stable versions prior to 2.8.3 and beta versions prior 2.9.0.beta4 erroneously expose groups. When a group with restricted visibility has been used to set the permissions of a category, the name of the group is leaked to any user that is able to see the category.

To workaround the problem, a site administrator can remove groups with restricted visibility from any category's permissions setting.
