Background
The @haxtheweb/haxcms-nodejs package is a Node.js application designed for managing content in the HAX CMS framework. It provides various API endpoints for file management, including listing and saving files. This package is widely used in web applications that require a content management system. However, it is vulnerable to a Denial of Service (DoS) attack due to improper handling of URL parameters in specific API requests.
Vulnerability Detail
The vulnerability arises from the application's failure to properly handle exceptions when required URL parameters are missing in API requests to the 'listFiles' and 'saveFiles' endpoints. An authenticated attacker can exploit this flaw by sending requests without the necessary parameters, causing the application to crash with an 'ERR_INVALID_ARG_TYPE' error. This results in a denial of service, preventing all users from accessing the backend system, which can severely impact any websites hosted by the application.
How To Fix

This can be done by validating the parameters before making the request, thus avoiding the crash. For example, check for the presence of parameters in your request code before proceeding with the API call.
Conclusion
The CVE-2025-54134 vulnerability in the @haxtheweb/haxcms-nodejs package poses a significant risk of denial of service due to improper error handling. It is crucial for users of this package to update to the latest version to mitigate this risk and ensure the stability of their applications.
