Critical Privilege Escalation Flaw Found in Aimogen Pro WordPress Plugin

Security researchers have identified a critical privilege escalation vulnerability, tracked as CVE-2026-15982, affecting the Aimogen Pro - All-in-One AI Content Writer, Editor, ChatBot & Automation Toolkit plugin for WordPress. This flaw, which carries a maximum CVSS score of 9.8, stems from a missing capability check in the 'aiomatic_call_google_ai_function' function, allowing unauthenticated actors to bypass security controls and execute arbitrary PHP code.

What's at Risk

The vulnerability impacts all versions of the Aimogen Pro plugin up to and including 2.8.4. Any WordPress site utilizing this plugin is currently at risk if it remains unpatched, particularly those that are internet-facing and accessible to the public.

Organizations relying on this toolkit for AI-driven content automation are prime targets, as the compromise of a WordPress administrative account can lead to full site takeover, data exfiltration, or the deployment of malicious payloads throughout the web server environment.

How the Flaw Works

This vulnerability is a classic example of an insecure access control flaw, where the application fails to verify the identity or permissions of a user before performing a sensitive action. In general, when an application exposes internal functions to the public without authentication, it allows attackers to interact with backend processes that were intended only for administrators.

By leveraging such a flaw, an attacker can typically manipulate the application's internal logic. In this specific case, the ability to clear function blacklists and execute arbitrary PHP functions allows an attacker to bypass standard security boundaries, potentially leading to the creation of unauthorized administrator accounts or the modification of site configuration files to maintain long-term persistence.

How to Protect Your Systems

• Update the Aimogen Pro plugin to the latest available version immediately to resolve the missing capability check.
• Remove the plugin entirely if a patch is not immediately available or if the functionality is no longer required for your operations.
• Implement the principle of least privilege by ensuring that only necessary plugins are installed and that administrative access is restricted to trusted personnel.
• Monitor your WordPress site's user database and server logs for unauthorized account creation or suspicious administrative activity.
• Enforce multi-factor authentication (MFA) for all administrative accounts to provide an additional layer of defense against unauthorized access.

Given the critical severity of this vulnerability and the ease with which it can be exploited by unauthenticated attackers, prompt action is essential. Failure to address this flaw leaves your entire web infrastructure vulnerable to full compromise, making immediate patching the most effective way to secure your environment against potential exploitation.
