CyberRota Analysis

AI-Generated

The vulnerability affects the Plate rich-text editor in Java versions 53.0.0 to 53.1.4, where improper validation of media embed URLs allows attackers to inject malicious JavaScript via crafted documents. This can lead to cross-site scripting (XSS) attacks when a victim opens the compromised document, potentially compromising user data and session integrity. Organizations using affected versions of Plate should prioritize updating to version 53.1.4 to mitigate this high-severity risk.

Original NVD Description

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.
