Summary
All versions of `marky-markdown` are vulnerable to HTML Injection. The package fails to sanitize `style` attributes in `img` tags of the markdown input. This may allow attackers to affect the size of images in the rendered HTML.
## Recommendation
This package is no longer maintained. Please upgrade to `@npmcorp/marky-markdown`
