How the Exploit Works

The vulnerability stems from a missing capability check on the check_activate_permission() permission callback for the /wp-json/presslearn/v1/activate REST API endpoint in the AL Pack plugin for WordPress. The callback reads the client-supplied Origin header and, after parsing, allows the request if it matches one of the trusted domains, without ever verifying user authentication, capabilities, or nonce tokens. As a result, unauthenticated attackers can activate premium features by simply spoofing the Origin header.

Conceptual Example Code

Here’s a conceptual HTTP request that could potentially exploit this vulnerability:

POST /wp-json/presslearn/v1/activate HTTP/1.1
Host: target.example.com
Origin: trusted.example.com
Content-Type: application/json
{ "premium_features": "activate" }

In this example, the attacker spoofs the Origin header to match a trusted domain, thereby bypassing the permission check and activating the premium features.

Recommended Mitigation Steps

To mitigate this vulnerability, it’s recommended to apply the vendor patch. In its absence, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as a temporary solution. Regularly updating and patching software is an essential part of maintaining an effective security posture.
