A path traversal vulnerability has been identified in the taoofagi easegen-admin application, specifically in versions prior to 8f87936ac774065b92fb20aab55b274a6ea76433. The issue arises in the recognizeMarkdown function within the Pdf2MdUtil.java file, where the fileUrl parameter is not properly validated.

The vulnerability requires authentication to exploit.
