Details

Sanitization bypass using HTML Entities in marked Affected versions of `marked` are susceptible to a cross-site scripting vulnerability in link components when `sanitize:true` is configured. ## Proof of Concept This flaw exists because link URIs containing HTML entities get processed in an abnormal manner. Any HTML Entities get parsed on a best-effort basis and included in the resulting link, while if that parsing fails that character is omitted. For example: A link URI such as ``` javascript&#x58document;alert&#40;1&#41; ``` Renders a valid link that when clicked will execute `alert(1)`. ## Recommendation Update to version 0.3.6 or later.
