Name of the Vulnerable Software and Affected Versions
Plate versions 53.0.0 through 53.1.3
Description
The media embed renderer trusts serialized provider or
sourceUrl metadata in useMediaState and skips parseMediaUrl protocol validation. This allows a crafted document to specify a known video provider while maintaining the url as a javascript: iframe source. The MediaEmbedElement then renders this directly as an iframe src when a user opens the document.Recommendations
Update to version 53.1.4.
