How to Fix CVE-2025-49139

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

@haxtheweb/haxcms-nodejs fixed: 11.0.0 
npm install @haxtheweb/haxcms-nodejs@11.0.0
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 @haxtheweb/haxcms-nodejs

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-49139, inspect your project dependencies using npm:

npm ls @haxtheweb/haxcms-nodejs

Analyze the terminal output to locate any version of @haxtheweb/haxcms nodejs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.0.0), your application is affected.

Note: The npm ls @haxtheweb/haxcms-nodejs 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-1021: Improper Restriction of Rendered UI Layers or Frames, where the web application does not restrict or incorrectly restricts frame objects or ui layers that belong to another application or domain. In @haxtheweb/haxcms nodejs, 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

### Summary In the HAX site editor, users can create a website block to load another site in an iframe. The application allows users to supply a target URL in the website block. When the HAX site is visited, the client's browser will query the supplied URL. ### Affected Resources - [Operations.php:868](https://github.com/haxtheweb/haxcms-php/blob/master/system/backend/php/lib/Operations.php#L868) - `https://<site>/<user>/system/api/saveNode` ### PoC 1. Set the URL in an iframe pointing to an attacker-controlled server running Responder ![image](https://github.com/user-attachments/assets/baac23ec-7b1e-49cf-864d-c3550b2c71bf) 2. Once another user visits the site, they are prompted to sign in. ![image](https://github.com/user-attachments/assets/a3a0b75d-e12f-49cf-8669-9686353a92e2) 3. If a user inputs credentials, the username and password hash are outputted in Responder. ![image](https://github.com/user-attachments/assets/428542d3-8cf5-4bfa-b759-e630c3ee6ac3) ### Impact An authenticated attacker can create a HAX site with a website block pointing at an attacker-controlled server running Responder or a similar tool. The attacker can then conduct a phishing attack by convincing another user to visit their malicious HAX site to harvest credentials.
