CVE-2022-50683
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA stored cross-site scripting vulnerability in Kentico Xperience allows attackers to inject malicious scripts via form redirect URL configuration. This allows malicious scripts to execute in users' browsers through unvalidated form configuration settings.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA stored cross-site scripting (XSS) vulnerability in Kentico Xperience allows attackers to inject malicious JavaScript through unvalidated form redirect URL configuration settings. The malicious payload is stored in the CMS configuration and executes in users' browsers when they encounter the affected form redirect.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Kentico Xperience versionAccess the Kentico Xperience administration interface and navigate to the 'About' or 'Version' section typically found under Help or Settings. Alternatively, check the version file in the installation directory if accessible.Affected if The installed version is 13.0.74 or lower (any version up to and including 13.0.74).
-
Identify forms with redirect URL configurationIn the Kentico Xperience admin interface, browse to the Forms application. Review each form's settings, specifically looking for fields related to redirect URLs, 'Redirect after submission', or 'Form redirect' configuration options.Affected if Forms exist that have redirect URL settings configured, especially those allowing custom or external URLs.
-
Inspect stored redirect URL valuesWithin each form's configuration where redirect URLs are defined, examine the stored URL values. Look for any redirect URLs that contain HTML tags, JavaScript protocols (javascript:), or unusual encoding.Affected if Any form redirect URL contains script-related content such as 'javascript:' or contains HTML/script tags in the URL field.
-
Check form submission behaviorSubmit a test form that has a redirect URL configured. Observe whether the redirect occurs and inspect the browser developer tools network tab to see the exact redirect URL being used.Affected if The redirect URL contains unsanitized user-supplied content or executes JavaScript when the form is submitted and the redirect occurs.
A user is affected if running Kentico Xperience version 13.0.74 or lower AND has forms configured with redirect URLs that may contain unsanitized or malicious content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement strict input validation and output encoding for form redirect URL fields in Kentico Xperience admin interface. Sanitize any user-supplied redirect URL values before storage and properly encode output when rendering redirect URLs.
Xperience version > 13.0.74 (consult Kentico's official release notes for the specific fixed version)
- Upgrade Kentico Xperience to a version higher than 13.0.74 that includes the security fix for this vulnerability
- After upgrading, verify that form redirect URL configurations are properly sanitized
- Review form configurations in the administration interface to ensure no malicious scripts were previously injected
- Test form submissions with various inputs to confirm the XSS vulnerability is remediated
