Overview
In the realm of WordPress plugins, a new vulnerability has been identified which poses significant threats to users of the Profitori plugin. This vulnerability, known as CVE-2025-4631, exposes these users to a potential privilege escalation exploit. In essence, this means that an unauthenticated attacker could potentially elevate the privileges of an existing user account, or even a newly created one, to that of an administrator. This is a grave concern, as it presents a potential avenue for system compromise or data leakage, and hence warrants immediate attention and action.

How the Exploit Works
The vulnerability lies in the stocktend_object endpoint of the Profitori plugin for WordPress. This endpoint lacks a necessary capability check, which results in the triggering of the save_object_as_user() function for objects whose ‘_datatype’ is set to ‘users’. As a result, this allows unauthenticated attackers to write arbitrary strings straight into the user’s wp_capabilities meta field.
In simpler terms, the absence of a check mechanism allows attackers to manipulate user capabilities, potentially elevating a user’s privileges to that of an administrator. Consequently, this can lead to unauthorized access to sensitive data and potentially compromise the entire system.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited:
POST /stocktend_object HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"_datatype": "users",
"wp_capabilities": "{administrator:1}"
}In this example, an attacker sends a malicious HTTP POST request to the stocktend_object endpoint. By setting the _datatype to ‘users’ and manipulating the wp_capabilities meta field, the attacker could potentially escalate user privileges to the administrator level.
Recommended Mitigation
To mitigate this vulnerability, users of the Profitori WordPress Plugin should apply the vendor patch as soon as possible. In case the patch is not immediately available, users can resort to using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) for temporary mitigation. However, this is intended only as a stopgap measure and not a long-term solution. The long-term solution would be to apply the vendor patch to close the vulnerability entirely.
