How to Fix CVE-2019-11358

To remediate this vulnerability, upgrade all affected Jquery dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

jquery fixed: 3.4.0

npm install jquery@3.4.0

jquery-rails fixed: 4.3.4

Upgrade jquery-rails to 4.3.4

jQuery fixed: 3.4.0

Upgrade jQuery to 3.4.0

django fixed: 2.1.9

pip install django>=2.1.9

django fixed: 2.2.2

pip install django>=2.2.2

org.webjars.npm:jquery fixed: 3.4.0

<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>jquery</artifactId>
    <version>3.4.0</version>
</dependency>

maximebf/debugbar fixed: 1.19.0

Upgrade maximebf/debugbar to 1.19.0

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls jquery

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-11358, inspect your project dependencies using npm:

npm ls jquery

Analyze the terminal output to locate any version of Jquery in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.4.0), your application is affected.

Note: The npm ls jquery command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Jquery, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

jQuery from 1.1.4 until 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles `jQuery.extend(true, {}, ...)` because of `Object.prototype` pollution. If an unsanitized source object contained an enumerable `__proto__` property, it could extend the native `Object.prototype`.
