Stored XSS via unsanitized iframe source

Published Apr 4, 2025 · Updated Apr 4, 2025

Stored XSS in React Draft WYSIWYG 1.15.0 and earlier allows remote attackers to execute script through a crafted Embedded link. The Embedded control accepts a javascript: URL without scheme validation and preserves it as an iframe source. Exploitation requires user interaction with the crafted embed; script then runs in the consuming application's browser origin and can expose or alter that user's data.
