Summary

In Argo CD version v1.5.0, a user enumeration vulnerability was identified, enabling malicious actors to deduce the existence of valid usernames. This vulnerability arises from the behavior of the /api/v1/session endpoint, which returns a 401 status code for existing (non-SSO) usernames and a 404 for non-existing ones. This discrepancy can be exploited by attackers to gather sensitive information about user accounts, leading to potential unauthorized access attempts. The vulnerability was resolved in version v1.5.1.
