Detailed vulnerability description
The vulnerability allows a remote user to disclose sensitive information and modify patient insurance data.
The vulnerability exists due to improper access control in document and insurance REST endpoints in apis/routes/_rest_routes_standard.inc.php when handling API requests with a valid bearer token. A remote user can send crafted requests for arbitrary patient identifiers to disclose sensitive information and modify patient insurance data.
The affected routes omit authorization checks that are used by other patient routes, allowing access across patient records regardless of the token's assigned ACLs.
