How to Fix CVE-2024-6531

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release.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 fixed: 5.0.0 
npm install bootstrap@5.0.0
bootstrap fixed: 5.0.0 
Upgrade bootstrap to 5.0.0
bootstrap fixed: 5.0.0 
Upgrade bootstrap to 5.0.0
bootstrap.sass fixed: 5.0.0 
Upgrade bootstrap.sass to 5.0.0
twbs/bootstrap fixed: 5.0.0 
Upgrade twbs/bootstrap to 5.0.0
org.webjars:bootstrap fixed: 5.0.0 
<dependency>
    <groupId>org.webjars</groupId>
    <artifactId>bootstrap</artifactId>
    <version>5.0.0</version>
</dependency>
org.webjars.npm:bootstrap fixed: 5.0.0 
<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>bootstrap</artifactId>
    <version>5.0.0</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 bootstrap

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-6531, inspect your project dependencies using npm:

npm ls bootstrap

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.0.0), your application is affected.

Note: The npm ls bootstrap 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 In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing.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

## Withdrawn Advisory This advisory is withdrawn because it was not a security issue in Bootstrap. Bootstrap’s JavaScript is not intended to sanitize unsafe or intentionally dangerous HTML. As such, the reported behavior fell outside the scope of Bootstrap’s security model, and the associated CVE has been rescinded. ## Original Descripton A vulnerability has been identified in Bootstrap that exposes users to Cross-Site Scripting (XSS) attacks. The issue is present in the carousel component, where the data-slide and data-slide-to attributes can be exploited through the href attribute of an <a> tag due to inadequate sanitization. This vulnerability could potentially enable attackers to execute arbitrary JavaScript within the victim's browser.
