| Package | Affected versions | Patched versions |
|---|---|---|
| remark-html | ≥ 14.0.0, < 14.0.1< 13.0.2 | 14.0.113.0.2 |
| remark-html | ≥ 14.0.0, < 14.0.1< 13.0.2 | 14.0.113.0.2 |
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.
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.
On older affected versions, pass sanitize: true, like so:
- .use(remarkHtml)
+ .use(remarkHtml, {sanitize: true})
