Overview
The Offsprout Page Builder plugin for WordPress has been identified as having a significant security vulnerability, specifically a privilege escalation vulnerability. This flaw, designated as CVE-2025-4672, affects versions 2.2.1 to 2.15.2 of the plugin. It allows authenticated attackers with Contributor-level access and above to manipulate user meta, including their own wp_capabilities, thereby escalating their privileges to the level of administrator.

How the Exploit Works
The exploit takes advantage of insufficient authorization checks in the permission_callback() function of the Offsprout plugin. An attacker with Contributor-level access or above is able to send crafted requests that modify the user meta data. This could include changing their own wp_capabilities to that of an administrator, thus allowing them to perform any administrative task on the WordPress site. This includes reading, creating, updating, or deleting any content on the site.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited using a crafted HTTP request to the vulnerable endpoint.
POST /wp-json/offsprout/v1/users/1 HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer [access_token]
{
"meta": {
"wp_capabilities": {
"administrator": "1"
}
}
}In this example, the attacker sends a POST request to the Offsprout endpoint for user updates. The request includes a JSON body that changes the wp_capabilities of the user to administrator. This would grant the attacker full administrative privileges on the WordPress site.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the latest patch provided by the vendor. If a patch is not immediately available, using a Web Application Firewall(WAF) or Intrusion Detection System(IDS) can provide temporary protection by identifying and blocking malicious requests.
