[renovate]

This PR contains the following updates:

Package	Change	Age	Adoption	Passing	Confidence
remark-html	^9.0.0 -> ^13.0.0

GitHub Vulnerability Alerts

CVE-2021-39199

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:

-  .use(remarkHtml)
+  .use(remarkHtml, {sanitize: true})

v13.0.2

Compare Source

• b0b1ba5 Fix to sanitize by default
  The docs have always said remark-html is safe by default. It wasn’t and this patches that.

  If you do want to be unsafe, use remark-html with sanitize: false:

  -  .use(remarkHtml)
  +  .use(remarkHtml, {sanitize: false})
