CVE-2026-85022Public exploitNetwork attack vectorHinoki check available

Authenticated script execution via unvalidated redirect URL

Published Sep 3, 2026 · Updated Sep 3, 2026

Cross-site scripting in Dify 1.13.0 WebApp Sign-In allows remote authenticated users to execute script through a crafted redirect_url. The mail-and-password-auth.tsx component passes the query parameter directly to router.replace without restricting the destination or URI scheme. Exploitation requires valid web-app credentials and user interaction with the crafted sign-in URL, and the script can modify content in the Dify origin.
