What is GHSA-v9wp-8r97-v6xg?

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 ` ` 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.

How do I mitigate GHSA-v9wp-8r97-v6xg if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-v9wp-8r97-v6xg?

O3 pinpoints whether GHSA-v9wp-8r97-v6xg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-v9wp-8r97-v6xg actively exploited in the wild?

No public exploit code has been indexed for GHSA-v9wp-8r97-v6xg yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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.
