Root Cause Analysis

The vulnerability stems from improper handling of the CKEditorFuncNum parameter in upload.php. Analysis of the GitHub issue #180 and PR #186 shows the XSS occurs because:

The $_GET['CKEditorFuncNum'] parameter is stored without sanitization in uploader.php
This value is later used in a JavaScript context in the response generation
The fix involved adding htmlentities() and character filtering for this parameter
The vulnerable code path starts in the uploader class constructor where the parameter is first processed, making this the root vulnerable function.
