How the Exploit Works
The CVE-2025-39536 vulnerability is due to missing authorization checks in the Chimpstudio JobHunt Job Alerts software. This missing authorization can allow an unauthenticated attacker to bypass access control security levels and perform actions that would otherwise require authentication. These actions could include viewing, modifying, or deleting sensitive data or even executing arbitrary commands with system-level privileges.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited:
POST /jobhunt/alerts HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"action": "delete",
"target": "all"
}In this example, an attacker sends a POST request to the job alerts endpoint. The “action” field is set to “delete”, and the “target” field is set to “all”, indicating that all job alerts are to be deleted. Because of the missing authorization check, this request could potentially be processed without any authentication, leading to a loss of data.
