Summary

The novel project by xxyopen and 201206030, up to 3.5.0, has an authorization bypass in the getBookChapter function of BookServiceImpl.java. The flaw is an improper authorization check on a user-controlled key (CWE-639), so manipulating the chapterId argument skips access control. A remote attacker with low privileges can access book chapters without authorization. A public exploit is linked in the references.
