Additional Advisory Data

Workarounds

CNA: For RadPdfViewer, handle the LinkAnnotationTapped event, set Handled to true and launch only URIs with trusted schemes (http, https, mailto, tel). RadRichTextEditor has no equivalent event in the affected versions, so avoid loading documents from untrusted sources or upgrade to the fixed version.
