selectize-plugin-a11y fixed: 1.1.0 
npm install selectize-plugin-a11y@1.1.0
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 selectize-plugin-a11y

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-15482, inspect your project dependencies using npm:

npm ls selectize-plugin-a11y

Analyze the terminal output to locate any version of Selectize plugin a11y in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: The npm ls selectize-plugin-a11y 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 Selectize plugin a11y, 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

Versions of `selectize-plugin-a11y ` prior to 1.1.0 are vulnerable to Cross-Site Scripting. The `accessibility.liveRegion.speak` function does not sanitize the `msg` variable before rendering it as HTML. If this variable is controlled by user input it allows attackers to execute arbitrary JavaScript in a victim's browser. ## Recommendation Upgrade to version 1.1.0 or later.
