What is Zulip?

Zulip is an open-source group chat application. It's designed for teams of any size - as small as 2 people and as large as hundreds of thousands. It allows users to organize discussions around a shared topic, like a product, company, or project.
Zulip was created because alternatives like Slack became too expensive for most organizations and mediums of communication like email are too complicated when you have a team of people with different preferences. Zulip allows you to create your own private workspace that's completely customizable and has features like file sharing and bots.

Check your Zulip server version. If it is at 5.5 or above, the vulnerability has been resolved. If you are still unable to upgrade, contact support@zonpi.com for assistance.
