The vulnerability stemmed from rendering PDF previews without sanitizing JavaScript content. The patches introduced PDF scanning checks (getResponseByScanStatus) in both getPreviewDocumentAction and showVersionAction, confirming these were the entry points for unsanitized content. The pre-patch code lacked these security checks, making these functions directly responsible for the XSS vulnerability.
