CVE-2026-46492: Commenthol Md-Fileserver

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

md-fileserver allows for local viewing of markdown files in a browser. Prior to version 1.10.3, a cross-site scripting (XSS) vulnerability exists in the application’s Markdown rendering logic. When user-supplied Markdown content is rendered, embedded raw HTML—including <script> tags—is processed and injected into the resulting page without sanitization, allowing arbitrary JavaScript execution in the context of the affected domain. This issue has been patched in version 1.10.3.

Affected products
