    Issue
    Impact The documentation of remark-html has mentioned that it was safe by default. In practise the default was never safe and had to be opted into. This means arbitrary HTML can be passed through leading to potential XSS attacks. Patches The problem has been patched in 13.0.2 and 14.0.1: remark-html is now safe by default, and the implementation matches the documentation. Workarounds On older affected versions, pass sanitize: true, like so: References n/a For more information If you have any questions or comments about this advisory: Open an issue in remark-html Email us at security@unifiedjs.com

    Recommended action: Upgrade to 14.0.1 or 13.0.2 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
