Cross-Site Scripting in jquery.json-viewer

Versions of jquery.json-viewer prior to 1.3.0 are vulnerable to Cross-Site Scripting (XSS). The package insufficiently sanitizes user input when creating links, and concatenates the user input in an <a> tag. This allows attackers to create malicious links with JSON payloads such as:

{
  "foo": "https://bar.com\" onmouseover=alert('xss') \""
}

This may lead to arbitrary JavaScript execution in a victim's browser.

Recommendation

Upgrade to version 1.3.0 or later.
