How the Exploit Works

CVE-2025-26730 exploits a vulnerability in the NotFound Macro Calculator software which allows unauthorized access to sensitive system information. An attacker could exploit this vulnerability by sending a specially crafted request to the server, causing it to expose sensitive system information. This information could be used for further attacks or even to compromise the entire system.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This example is a malicious HTTP request:

POST /vulnerable/system-info HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "exploit_payload": "request_system_info" }

In this example, the attacker sends a POST request to the vulnerable /system-info endpoint. The server, upon receiving the request, inadvertently exposes sensitive system information that could be used for further attacks or system compromise.
