| Título | xxyopen novel-plus v5.1.3 Improper Authorization |
|---|
| Descripción | The `remove` endpoint in `FileController.java` is vulnerable to an Insecure Direct Object Reference (IDOR) attack due to improper authorization. The function accepts a file `id` for deletion but fails to verify if the currently authenticated user is the owner of the file. As a result, any authenticated user can delete any file stored in the system by simply knowing or guessing its `id`. The intended permission check `@RequiresPermissions` is notably commented out in the source code, making the vulnerability explicit. |
