CVE-2025-24981

Summary

CVE-2025-24981 is a vulnerability affecting the Markdown to Vue component (MDC) tool. In affected versions, the tool's URL parsing logic in `props.ts` is unsafe and can lead to Arbitrary JavaScript Code Execution due to a bypass of the existing guards around the `javascript:` protocol scheme. An attacker can provide JavaScript URLs with HTML entities encoded via hex strings to bypass these security guards, resulting in XSS vulnerabilities in markdown parsing from unvalidated sources. This issue has been resolved in version 0.13.3 and all users are urged to upgrade. There are currently no known workarounds for this vulnerability.
