Privilege escalation via collaborative script macro execution
Published Jan 14, 2025 · Updated Jan 15, 2025
Missing authorization in XWiki Platform allows remote authenticated users with edit rights to escalate privileges through realtime editing. A script rendering macro inserted into shared WYSIWYG content is re-rendered for a collaborator with script or programming rights, executing with that collaborator's authority. Exploitation requires the experimental realtime extension, an editable page, and a higher-privileged user to join the same session.
