Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada zulip server. Skor CVSS 3.1 5.4 (Medium) menurut NVD.

Deskripsi (NVD)

Zulip is an open source team chat app. The `main` development branch of Zulip Server from June 2021 and later is vulnerable to a cross-site scripting vulnerability on the recent topics page. An attacker could maliciously craft a full name for their account and send messages to a topic with several participants; a victim who then opens an overflow tooltip including this full name on the recent topics page could trigger execution of JavaScript code controlled by the attacker. Users running a Zulip server from the main branch should upgrade from main (2022-03-01 or later) again to deploy this fix.
