The vulnerability identified as CVE-2025-0429 affects the 'AI Power: Complete AI Pack' WordPress plugin developed by senols. It is a PHP Object Injection vulnerability stemming from unsafe deserialization of untrusted input in the wpaicg_export_ai_forms() function, specifically via the $form['post_content'] variable. Deserialization of untrusted data (CWE-502) can allow attackers to manipulate application logic by injecting crafted serialized PHP objects. In this case, the attacker must be authenticated with administrative privileges to exploit the flaw, which limits the attack surface but still poses a significant risk. The plugin does not include a POP (Property Oriented Programming) gadget chain internally, which is typically required to achieve code execution. However, if other plugins or themes installed on the same WordPress instance contain suitable POP chains, an attacker could leverage this vulnerability to execute arbitrary code, delete files, or access sensitive information. The vulnerability is present in all versions up to and including 1.8.96. The CVSS 3.1 score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) indicates network exploitable with low complexity but requiring high privileges and no user interaction, impacting confidentiality, integrity, and availability. No patches or exploit code are currently publicly available, but the risk remains high due to the potential impact and the widespread use of WordPress plugins.

If exploited, this vulnerability could lead to severe consequences for affected organizations. An attacker with administrative access could inject malicious PHP objects, potentially leading to remote code execution if a suitable POP chain exists in the environment. This could result in full system compromise, including unauthorized data access, data modification, or deletion of critical files. The integrity and availability of the WordPress site and underlying server could be severely impacted, potentially causing service outages or data breaches. Given the plugin's AI-related functionality, sensitive AI-generated content or configurations could also be exposed or manipulated. Organizations relying on this plugin for AI capabilities in WordPress are at risk of targeted attacks, especially if they have additional plugins or themes that provide exploitable POP chains. The requirement for administrative privileges reduces the risk from external unauthenticated attackers but does not eliminate the threat from insider threats or compromised admin accounts.

To mitigate this vulnerability, organizations should immediately update the 'AI Power: Complete AI Pack' plugin once a patch is released by the vendor. Until a patch is available, administrators should restrict access to trusted users only and review administrative account security, including enforcing strong authentication and monitoring for suspicious activity. Disable or remove unnecessary plugins and themes that could provide POP chains to reduce the attack surface. Implement Web Application Firewalls (WAFs) with rules to detect and block suspicious serialized PHP payloads targeting the vulnerable function. Conduct regular security audits and code reviews of installed plugins and themes to identify potential gadget chains. Additionally, consider isolating WordPress instances or running them with least privilege to limit the impact of a successful exploit. Backup WordPress sites and databases regularly to enable recovery in case of compromise. Finally, educate administrators about the risks of deserialization vulnerabilities and the importance of cautious plugin management.
