What is CVE-2026-40480?
CVE-2026-40480 is a high-severity missing authorization vulnerability in ChurchCRM CRM, published on 17 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the GET /api/person/{personId} endpoint loads and returns person records without performing object-level authorization checks. Although the legacy PersonView.php page enforces canEditPerson() restrictions, the API layer omits this check. Any authenticated user with only EditSelf privileges can enumerate and read other members' records, exposing sensitive PII including names, addresses, phone numbers, and email addresses. This issue has been fixed in version 7.2.0.
