## Technical details

An improper access control vulnerability (CWE-284/CWE-266) exists in TaleLin lin-cms-spring-boot version 0.2.1 and earlier within the BookController.java component. The endpoints for creating books (POST /v1/book) and updating books (PUT /v1/book/{id}) lack necessary permission verification or authorization checks. A remote attacker with low privileges can exploit these endpoints to inject arbitrary book records or modify existing records by enumerating predictable ID parameters. While the advisory mentions remote exploitability, the CVSS vector indicates low privileges (PR:L) are required. As of the publication date, the project maintainers have not responded to the issue report.
