CVE-2026-40485 Details
Description
ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the public API login endpoint (/api/public/user/login) returns distinguishable HTTP response codes based on whether a username exists: 404 for non-existent users and 401 for valid users with incorrect passwords. An unauthenticated attacker can exploit this difference to enumerate valid usernames, with no rate limiting or account lockout to impede the process. This issue has been fixed in version 7.2.0.
A username enumeration vulnerability has been identified in ChurchCRM versions prior to 7.2.0. The issue arises in the public API login endpoint, which returns different HTTP response codes based on the existence of a username. A 404 status is issued for non-existent users, while a 401 status is given for valid users with incorrect passwords. This discrepancy allows an unauthenticated attacker to systematically identify valid usernames without facing any rate limiting or account lockout. The vulnerability has been patched in version 7.2.0.
Users can upgrade to ChurchCRM version 7.2.0 or later, where this vulnerability has been fixed.
