CVE-2022-31025
June 03, 2022
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.
