MoguBlog through 6.2 contains an authorization bypass vulnerability in the POST /pictureSort/getPictureSortByUid endpoint, which omits the @AuthorityVerify annotation required to enforce role-based permissions. Authenticated back-office users without image-category permissions can supply a category uid to retrieve restricted image-category records including metadata such as name, cover file uid, sort order and timestamps.
