Unauthenticated book disclosure via unguarded getBooks endpoint
Published Sep 24, 2026 · Updated Sep 24, 2026
Improper authorization in TaleLin Lin CMS Spring Boot 0.2.0 through 0.2.1 allows remote attackers to read every stored book record. GET /v1/book invokes BookController.getBooks, which returns bookService.findAll without an access-control annotation. No authentication is required at this endpoint, and the grounded consequence is limited to disclosure of book data rather than modification.
