CyberRota Analysis
AI-GeneratedThe vulnerability affects the File Viewer component in Office and Java applications, allowing crafted legacy DOC files to generate unsafe hyperlink targets that could execute scripts in the embedding application's origin. This poses a significant risk of cross-site scripting (XSS) attacks when users interact with malicious links. Organizations using affected versions should prioritize applying the updates to @file-viewer/doc 2.3.1 and msdoc-viewer 0.2.2 to mitigate potential exploitation.

Original NVD Description
File Viewer is a browser-native viewer for Office, PDF, CAD, archive, and other files in private and internal web applications. Prior to @file-viewer/doc 2.3.1 and msdoc-viewer 0.2.2, the legacy DOC renderer emitted document-controlled hyperlink targets into generated HTML after character escaping but without restricting URL schemes. A crafted legacy DOC file could place javascript:, vbscript:, data:, or another unsafe scheme in a rendered link, and script could execute in the embedding application's origin when a user clicked the link. The fix blocks external document links by default, allows only HTTP(S), mail, telephone, safe relative URLs, and internal bookmarks when external links are explicitly enabled, and applies mount-boundary sanitization as defense in depth. This issue is fixed in @file-viewer/doc 2.3.1 and msdoc-viewer 0.2.2.
