CVE-2023-38051Network attack vector

Authenticated secretary record takeover via unchecked object IDs

Published Jul 9, 2024 · Updated Aug 2, 2024

Broken object authorization in Easy!Appointments before 1.5.0 allows remote authenticated users to read, modify, or delete secretary records. The GET, PUT, and DELETE /secretaries/{secretaryId} handlers trust the path identifier without verifying entitlement to the referenced secretary object. Any low-privileged account with REST API access can target another low-privileged secretary's data; administrator records are not reported as affected.
