Lifecycle Timeline
1DescriptionNVD
Zulip is an open-source team collaboration tool with topic-based threading that combines email and chat.

For example, a user may be able to edit or delete their old messages they posted in such a private stream. An administrator will be able to delete old messages (that they had access to) from the private stream. This issue was fixed in Zulip Server version 7.3.
