| Titel | ChurchCRM ChurchCRM (GitHub: ChurchCRM/CRM) <= 5.18.0 Authentication Bypass / Access Control |
|---|
| Beschreibung | A critical authentication bypass in ChurchCRM’s API middleware allows unauthenticated attackers to access protected API endpoints by including the substring api/public anywhere in the request URI (path, query string, or fragment). The middleware used str_contains($request->getUri(), 'api/public'), which matched the full URI instead of only the path. An attacker can bypass authentication by adding a query parameter such as ?bypass=api/public, resulting in exposure and potential modification of sensitive data (member records, family relationships), triggering background jobs, abusing geocoding endpoints, and deleting calendar entries where allowed. |
