How to Fix CVE-2024-21490

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

angular fixed: Latest secure release 
npm install angular@Latest secure release
org.webjars.npm:angular fixed: Latest secure release 
<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>angular</artifactId>
    <version>Latest secure release</version>
</dependency>
org.webjars.bower:angular fixed: Latest secure release 
<dependency>
    <groupId>org.webjars.bower</groupId>
    <artifactId>angular</artifactId>
    <version>Latest secure release</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 angular

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-21490, inspect your project dependencies using npm:

npm ls angular

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

Note: The npm ls angular 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Angular, 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

This affects versions of the package angular from 1.3.0. A regular expression used to split the value of the ng-srcset directive is vulnerable to super-linear runtime due to backtracking. With a large carefully-crafted input, this can result in catastrophic backtracking and cause a denial of service. **Note:** This package is EOL and will not receive any updates to address this issue. Users should migrate to [@angular/core](https://www.npmjs.com/package/@angular/core).
