CVE-2025-24981: MDC is a tool to take regular Markdown and write documents interacting deeply with a Vue component. In affected versions

MDC is a tool that converts Markdown into documents that work with Vue components (a JavaScript framework for building user interfaces). In affected versions, the tool has a security flaw where it doesn't properly validate URLs in Markdown, allowing attackers to sneak in malicious JavaScript code by encoding it in a special format (hex-encoded HTML entities). This can lead to XSS (cross-site scripting, where unauthorized code runs in a user's browser) if the tool processes untrusted Markdown.
