Session hijacking via unrestricted HTML material URLs

Published Jan 6, 2026 · Updated Jan 6, 2026

The /api/content-creation endpoint accepts an unauthenticated HTML material URL and embeds its remote content without restricting the source or script types. Execution occurs when an operator previews or displays the crafted material, enabling session hijacking and unauthorized changes to displayed content.
