CVE-2025-0429 in AI Power Plugin
Summary
by MITRE • 01/22/2025
The "AI Power: Complete AI Pack" plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.8.96 via deserialization of untrusted input from the $form['post_content'] variable through the wpaicg_export_ai_forms() function. This allows authenticated attackers, with administrative privileges, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The CVE-2025-0429 vulnerability affects the "AI Power: Complete AI Pack" WordPress plugin, representing a critical security flaw that exploits PHP Object Injection through improper input validation. This vulnerability exists in versions up to and including 1.8.96, making it a significant risk for WordPress installations that have not updated to newer versions. The flaw specifically occurs within the wpaicg_export_ai_forms() function where untrusted input from the $form['post_content'] variable is processed without adequate sanitization or validation mechanisms.
The technical exploitation of this vulnerability requires an authenticated attacker with administrative privileges, which significantly reduces the attack surface compared to vulnerabilities requiring lower privileges. However, the impact remains severe due to the nature of PHP Object Injection vulnerabilities that can lead to arbitrary code execution when combined with proper POP (Point of No Return) chains. The vulnerability stems from the plugin's failure to properly sanitize user input during the deserialization process, allowing maliciously crafted PHP objects to be instantiated and executed within the WordPress environment.
The operational impact of this vulnerability extends beyond simple code execution capabilities, as it provides attackers with the potential to perform destructive actions such as arbitrary file deletion, data exfiltration, and complete system compromise. The absence of a POP chain within the vulnerable plugin itself means that exploitation requires additional components within the target environment to create a complete attack vector. This characteristic makes the vulnerability particularly dangerous in environments where multiple plugins or themes are installed, as any additional component with vulnerable POP chains could be leveraged to achieve full system compromise.
Security practitioners should consider this vulnerability in the context of the CWE-502 weakness classification, which specifically addresses "Deserialization of Untrusted Data" as a critical security concern. The ATT&CK framework would categorize this vulnerability under T1059.007 for "Command and Scripting Interpreter: Python" or similar execution techniques, depending on the payload delivered. Organizations should prioritize immediate patching of the vulnerable plugin to version 1.8.97 or later, as well as implementing comprehensive monitoring for unauthorized administrative activities. Additionally, security teams should conduct thorough audits of all installed plugins and themes to identify potential POP chains that could be exploited in conjunction with this vulnerability, ensuring that the entire WordPress ecosystem remains secure against such sophisticated attack vectors.
