How to Fix CVE-2025-2336

To remediate this vulnerability, upgrade all affected Angular sanitize 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-sanitize fixed: Latest secure release 
npm install angular-sanitize@Latest secure release
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-sanitize

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-2336, inspect your project dependencies using npm:

npm ls angular-sanitize

Analyze the terminal output to locate any version of Angular sanitize 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-sanitize 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-791: Incomplete Filtering of Special Elements, where the product receives data from an upstream component, but does not completely filter special elements before sending it to a downstream component. In Angular sanitize, 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

Improper sanitization of the value of the 'href' and 'xlink:href' attributes in '<image>' SVG elements in AngularJS's 'ngSanitize' module allows attackers to bypass common image source restrictions. This can lead to a form of Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing  and also negatively affect the application's performance and behavior by using too large or slow-to-load images. This issue affects AngularJS versions greater than or equal to 1.3.1. Note: The AngularJS project is End-of-Life and will not receive any updates to address this issue. For more information see here https://docs.angularjs.org/misc/version-support-status .
