Zulip vulnerable to insufficient authorization check for edition/deletion of messages and topics in private streams by former subscribers
Résumé
Zulip vulnerable to insufficient authorization check for edition/deletion of messages and topics in private streams by former subscribers
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Zulip is an open-source team collaboration tool with topic-based threading that combines email and chat. Users who used to be subscribed to a private stream and have been removed from it since retain the ability to edit messages/topics, move messages to other streams, and delete messages that they used to have access to, if other relevant organization permissions allow these actions. 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.
