CVE-2025-67717

Zitadel Discloses the Total Number of Instance Users

State: Published
Severity: 5.3 Medium
Published: Dec 11, 2025
Updated: Dec 11, 2025
Reserved: Dec 10, 2025

Description

ZITADEL is an open-source identity infrastructure tool. Versions 2.44.0 through 3.4.4 and 4.0.0-rc.1 through 4.7.1 disclose the total number of instance users to authenticated users, regardless of their specific permissions. While this does not leak individual user data or PII, disclosing the total user count via the totalResult field constitutes an information disclosure vulnerability that may be sensitive in certain contexts. This issue is fixed in versions 3.4.5 and 4.7.2.
