Security readout for executives and security teams
CVE-2014-3743 is an XSS flaw in the Marked Markdown parser before 0.3.1. If a website renders Markdown supplied by users or external systems, crafted content could cause script or HTML to run in another user’s browser. Business risk depends on whether Marked is exposed to untrusted content. Most likely exposed systems are Node.js applications using Marked before 0.3.1 to render untrusted Markdown into web pages, comments, documentation, profiles, tickets, or CMS content. Treat as a targeted remediation item for legacy Node.js assets. Prioritize internet-facing or authenticated multi-user applications where untrusted Markdown is rendered to other users. Mitigation focus: Upgrade Marked to 0.3.1 or later where present.; Check vendor or package advisory guidance for supported upgrade paths.; Avoid rendering untrusted Markdown without HTML and URL sanitization controls..
