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.

Attack-Flow Graph

Executive Summary

This vulnerability in ZITADEL versions 2.44.0 through 3.4.4 and 4.0.0-rc.1 through 4.7.1 allows authenticated users to see the total number of instance users via the totalResult field, regardless of their specific permissions. Although it does not expose individual user data or personally identifiable information (PII), disclosing the total user count is considered an information disclosure vulnerability that may be sensitive depending on the context.

Compliance Impact

The vulnerability discloses the total number of users in a Zitadel instance to any authenticated user, but it does not expose individual user data or personally identifiable information (PII). Therefore, while the total user count disclosure may be sensitive in certain contexts, it does not directly leak PII or sensitive personal data that would typically impact compliance with standards like GDPR or HIPAA. [2]

Impact Analysis

The impact of this vulnerability is limited to information disclosure of the total number of users in a ZITADEL instance. While it does not expose individual user details or PII, revealing the total user count could be sensitive in some contexts, potentially aiding attackers in understanding the scale of the user base or the environment, which might be leveraged in further attacks or reconnaissance.

Mitigation Strategies

Upgrade ZITADEL to version 3.4.5 or later, or 4.7.2 or later, where this information disclosure vulnerability has been fixed.
