Plate is a rich-text editor with AI and shadcn/ui. From 53.0.0 until 53.1.4, the media embed renderer trusts serialized provider or sourceUrl metadata in useMediaState and skips parseMediaUrl protocol validation, allowing a crafted Plate document to set a known video provider while keeping url as a javascript: iframe source that the registry MediaEmbedElement renders directly as an iframe src when a victim opens the document. This issue is fixed in version 53.1.4.

The media embed renderer trusts serialized provider/sourceUrl metadata in useMediaState and skips parseMediaUrl protocol validation, so an attacker can flag a URL as a legitimate video provider while keeping a javascript: payload that MediaEmbedElement renders directly as an iframe src. …
