Description
plugNmeet Server through 2.5.2 contains a path traversal vulnerability in the whiteboard conversion endpoint that allows any meeting participant to read server files via crafted filePath values. Attackers can supply ../ sequences so text or office documents are converted into page images, then fetch them unauthenticated through /download/uploadedFile/.
