Technical details

The /v1/book GET endpoint in BookController.java lacks access control verification, allowing unauthenticated remote access to the getBooks() method. The vulnerability exploits missing authorization checks on a REST API endpoint that queries the database; attackers can enumerate all books and their details by iterating through predictable ID values. The endpoint requires only a network request with no authentication or user interaction needed.

Affected products

TaleLin lin-cms-spring-boot up to 0.2.1
