CVE-2025-26953: Unauthorized Access Vulnerability in NotFound JetMenu

Views: 272

Overview

This report discusses CVE-2025-26953, a missing authorization vulnerability in NotFound JetMenu. This plugin vulnerability could allow attackers to bypass Access Control Lists (ACLs), potentially leading to system compromise or data leakage. It is a significant concern for all users of JetMenu versions up to 2.4.9, as it may result in unauthorized access to functionality not properly constrained by ACLs.

How the Exploit Works

The exploit takes advantage of a missing authorization flaw in JetMenu. An attacker can send specific requests to certain endpoints which are not properly constrained by ACLs. This allows the attacker to access and possibly modify data or functionality that they should not have access to, potentially leading to system compromise or data leakage.

Conceptual Example Code

An attacker could send a request similar to the following to exploit the vulnerability:

POST /unauthorized/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "unauthorized_request": "..." }

In this example, “unauthorized_request” represents data or functionality that the attacker is not authorized to access or modify, but due to the missing authorization vulnerability in JetMenu, the system erroneously processes the request.

Mitigation

To mitigate this vulnerability, users are advised to apply the vendor-supplied patch. If the patch is not yet available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure by blocking or alerting on attempts to exploit this vulnerability.
