marked@0.3.7 vulnerabilities

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) when passing unsanitized user input to inline.reflinkSearch, if it is not being parsed by a time-limited worker thread.

Upgrade marked to version 4.0.10 or higher.

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). The em regex within src/rules.js file have multiple unused capture groups which could lead to a denial of service attack if user input is reachable.

Upgrade marked to version 1.1.1 or higher.

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). A Denial of Service condition could be triggered through exploitation of the heading regex.

Upgrade marked to version 0.4.0 or higher.

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). The inline.text regex may take quadratic time to scan for potential email addresses starting at every point.

Upgrade marked to version 0.6.2 or higher.

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). This can cause an impact of about 10 seconds matching time for data 150 characters long.

Upgrade marked to version 0.3.18 or higher.

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). Browsers support both lowercase and uppercase x in hexadecimal form of HTML character entity, but marked unescaped only lowercase.

This may allow an attacker to create a link with javascript code.

For example:

var marked = require('marked');
marked.setOptions({
  renderer: new marked.Renderer(),
  sanitize: true
});

text = `
lower[click me](javascript:...)lower
upper[click me](javascript:...)upper
`;

console.log(marked(text));

will render the following:

<p>lowerlower
upper<a href="javascript&#X3a;...">click me</a>upper</p>

Upgrade marked to version 0.3.9 or higher.

marked is a low-level compiler for parsing markdown without caching or blocking for long periods of time.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). When mangling is disabled via option mangle, marked doesn't escape target href. This may allow an attacker to inject arbitrary html-event into resulting a tag.

For example:

var marked = require('marked');
marked.setOptions({
  renderer: new marked.Renderer(),
  sanitize: true,
  mangle: false
});

text = `
<bar"onclick="alert('XSS')"@foo>
`;

console.log(marked(text));

will render:

<p><a href="mailto:bar"onclick="alert('XSS')"@foo">bar"onclick="alert('XSS')"@foo</a></p>

Upgrade marked to version 0.3.9 or higher.
