CVE-2024-23345Network attack vector

Stored XSS via unsanitized rendered Markdown

Published Jan 22, 2024 · Updated May 30, 2025

Stored XSS in Network to Code Nautobot before 1.6.10 or 2.0.0 through 2.1.1 allows remote authenticated users to run scripts. The render_markdown utility renders user-editable Markdown to HTML and marks it safe after only stripping tags and filtering link schemes, which misses obfuscated script injection. Exploitation requires low-privileged write access to a Markdown-backed field and a user to view or click the rendered content, enabling actions in the viewer's session.
