CVE-2022-31096 – Invites restricted to an email or invite links restricted to an email domain may be bypassed by a under certain conditions in Discourse

https://notcve.org/view.php?id=CVE-2022-31096

Discourse is an open source discussion platform. Under certain conditions, a logged in user can redeem an invite with an email that either doesn't match the invite's email or does not adhere to the email domain restriction of an invite link. The impact of this flaw is aggravated when the invite has been configured to add the user that accepts the invite into restricted groups. Once a user has been incorrectly added to a restricted group, the user may then be able to view content which that are restricted to the respective group. Users are advised to upgrade to the current stable releases. • https://github.com/discourse/discourse/security/advisories/GHSA-rvp8-459h-282r • CWE-281: Improper Preservation of Permissions •

CVE-2022-31025 – Invite bypasses user approval in Discourse

https://notcve.org/view.php?id=CVE-2022-31025

Discourse is an open source platform for community discussion. Prior to version 2.8.4 on the `stable` branch and 2.9.0beta5 on the `beta` and `tests-passed` branches, inviting users on sites that use single sign-on could bypass the `must_approve_users` check and invites by staff are always approved automatically. The issue is patched in Discourse version 2.8.4 on the `stable` branch and version `2.9.0.beta5` on the `beta` and `tests-passed` branches. As a workaround, disable invites or increase `min_trust_level_to_allow_invite` to reduce the attack surface to more trusted users.
