CVSS: 5.3EPSS: 0%CPEs: 11EXPL: 0CVE-2022-21677 – Group advanced search option may leak group and group's members visibility
https://notcve.org/view.php?id=CVE-2022-21677
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. • https://github.com/discourse/discourse/commit/fff8b98485561b12d070c0a8c39f4e503813ab44 https://github.com/discourse/discourse/security/advisories/GHSA-768r-ppv4-5r27 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 8.8EPSS: 0%CPEs: 11EXPL: 0CVE-2022-21684 – User can bypass approval when invited to Discourse
https://notcve.org/view.php?id=CVE-2022-21684
Discourse is an open source discussion platform. Versions prior to 2.7.13 in `stable`, 2.8.0.beta11 in `beta`, and 2.8.0.beta11 in `tests-passed` allow some users to log in to a community before they should be able to do so. A user invited via email to a forum with `must_approve_users` enabled is going to be automatically logged in, bypassing the check that does not allow unapproved users to sign in. They will be able to do everything an approved user can do. If they logout, they cannot log back in. • https://github.com/discourse/discourse/commit/584c6a2e8bc705072b09a9c4b55126d6f8ed4ad2 https://github.com/discourse/discourse/security/advisories/GHSA-p63q-jp48-h8xh https://meta.discourse.org/t/invite-redemption-allowed-user-to-access-forum-before-approval/214328 • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2021-43850
Discourse is an open source platform for community discussion. In affected versions admins users can trigger a Denial of Service attack via the `/message-bus/_diagnostics` path.
