+info:
+  name: 3DPrint Lite < 1.9.1.5 - Arbitrary File Upload
+  author: securityforeveryone
+  severity: critical
+  description: |
+    The plugin does not have any authorisation and does not check the uploaded file in its p3dlite_handle_upload AJAX action , allowing unauthenticated users to upload arbitrary file to the web server. However, there is a .htaccess, preventing the file to be accessed on Web servers such as Apache.
+  remediation: Fixed in 1.9.1.5
