How to Fix CVE-2021-41182

To remediate this vulnerability, upgrade all affected Jquery ui 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-ui fixed: 1.13.0 
npm install jquery-ui@1.13.0
jQuery.UI.Combined fixed: 1.13.0 
Upgrade jQuery.UI.Combined to 1.13.0
jquery-ui-rails fixed: 7.0.0 
Upgrade jquery-ui-rails to 7.0.0
org.webjars.npm:jquery-ui fixed: 1.13.0 
<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>jquery-ui</artifactId>
    <version>1.13.0</version>
</dependency>
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-ui

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-41182, inspect your project dependencies using npm:

npm ls jquery-ui

Analyze the terminal output to locate any version of Jquery ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.13.0), your application is affected.

Note: The npm ls jquery-ui 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Jquery ui, 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

### Impact Accepting the value of the `altField` option of the Datepicker widget from untrusted sources may execute untrusted code. For example, initializing the datepicker in the following way: ```js $( "#datepicker" ).datepicker( { altField: "<img onerror='doEvilThing()' src='/404' />", } ); ``` will call the `doEvilThing` function. ### Patches The issue is fixed in jQuery UI 1.13.0. Any string value passed to the `altField` option is now treated as a CSS selector. ### Workarounds A workaround is to not accept the value of the `altField` option from untrusted sources. ### For more information If you have any questions or comments about this advisory, search for a relevant issue in [the jQuery UI repo](https://github.com/jquery/jquery-ui/issues). If you don't find an answer, open a new issue.
