CVE-2025-30369: Zulip allows the deletion of Custom profile fields by administrators of a different organization

Published Mar 31, 2025
·
Updated

Zulip is an open-source team collaboration tool. The API for deleting an organization custom profile field is supposed to be restricted to organization administrators, but its handler failed to check that the field belongs to the same organization as the user. Therefore, an administrator of any organization was incorrectly allowed to delete custom profile fields belonging to a different organization. This is fixed in Zulip Server 10.1.
