AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
What immediate steps should I take to mitigate this vulnerability?
Upgrade ZITADEL to version 3.4.5 or later, or 4.7.2 or later, where this information disclosure vulnerability has been fixed.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
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.
