Zulip 8.3 is vulnerable to Cross Site Scripting (XSS) via the replace_emoji_with_text function in ui_util.ts.

Zulip 8.3 is vulnerable to Cross Site Scripting (XSS) via the construct_copy_div function in copy_and_paste.js.

Zulip from 8.0 to 8.3 contains a memory leak vulnerability in the handling of popovers.

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.
