CVE-2025-30369
CWE-566Published: March 31, 2025· Updated: Jun 17, 2026
Official Description
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.
Technical Analysis
CVE-2025-30369 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
