Zulip is an open-source team collaboration tool. A vulnerability in version 8.0 is similar to CVE-2023-32677, but applies to multi-use invitations, not single-use invitation links as in the prior CVE. Specifically, it applies when the installation has configured non-admins to be able to invite users and create multi-use invitations, and has also configured only admins to be able to invite users to streams. As in CVE-2023-32677, this does not let users invite new users to arbitrary streams, only to streams that the inviter can already see. Version 8.1 fixes this issue. As a workaround, administrators can limit sending of invitations down to users who also have the permission to add users to streams.

The weakness was published 01/25/2024 as GHSA-87p9-wprh-7rm6. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2024-21630 since 12/29/2023. There are neither technical details nor an exploit publicly available.
