Authenticated browser script execution via unvalidated form redirect
Published Dec 18, 2025 · Updated Dec 18, 2025
Stored XSS in Kentico Xperience 13.0.74 and earlier allows remote authenticated users to execute scripts through form redirect settings. The “After the form is submitted > Redirect to URL” field stores input without proper validation and later emits it into a browser-executable redirect context. Low-privileged access to form configuration and a user loading the affected form flow are required; exploitation runs script in that user’s browser context.
