Description
Discourse is an open source discussion platform. Discourse groups can be configured with varying visibility levels for the group as well as the group members. By default, a newly created group has its visibility set to public and the group’s members visibility set to public as well. However, a group’s visibility and the group’s members visibility can be configured such that it is restricted to logged on users, members of the group or staff users. A vulnerability has been discovered in versions prior to 2.7.13 and 2.8.0.beta11 where the group advanced search option does not respect the group’s visibility and members visibility level. As such, a group with restricted visibility or members visibility can be revealed through search with the right search option. This issue is patched in stable version 2.7.13, beta version 2.8.0.beta11, and tests-passed version 2.8.0.beta11 versions of Discourse. There are no workarounds aside from upgrading.
