How to fix CVE-2026-40480?

Within 24 hours: Audit access logs for suspicious GET requests to /api/person/* endpoints and confirm current ChurchCRM version. Within 7 days: Upgrade ChurchCRM to version 7.2.0 or later immediately, as this is a critical authorization bypass affecting all authenticated users. Within 30 days: Conduct a full access audit of the person API endpoint to identify any unauthorized data extraction; notify affected members and leadership of the vulnerability and remediation steps; implement network-level API logging and alerting for person data access.

DescriptionNVD

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.

AnalysisAI

Broken object-level authorization in ChurchCRM 7.1.x and earlier allows authenticated users with minimal EditSelf privileges to enumerate and exfiltrate sensitive personal data (names, addresses, phone numbers, emails) of all church members via the unauthenticated GET /api/person/{personId} API endpoint. While legacy UI enforces canEditPerson() checks, the API layer completely omits these authorization controls, enabling horizontal privilege escalation. …
