How to Fix CVE-2025-47204

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

bootstrap-multiselect fixed: 2.0.0 
npm install bootstrap-multiselect@2.0.0
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 bootstrap-multiselect

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-47204, inspect your project dependencies using npm:

npm ls bootstrap-multiselect

Analyze the terminal output to locate any version of Bootstrap multiselect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.0), your application is affected.

Note: The npm ls bootstrap-multiselect 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 Bootstrap multiselect, 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

An issue was discovered in post.php in bootstrap-multiselect (aka Bootstrap Multiselect) 1.1.2. A PHP script in the source code echoes arbitrary POST data. If a developer adopts this structure wholesale in a live application, it could create a Reflective Cross-Site Scripting (XSS) vulnerability exploitable through Cross-Site Request Forgery (CSRF).
