Unknown Unknown - Not Provided

BaseFortify

Publication date: 2025-11-13

Last updated on: 2025-11-13

Assigner: Wordfence

Description
The AI Engine plugin for WordPress is vulnerable to PHP Object Injection via PHAR Deserialization in all versions up to, and including, 3.1.8 via deserialization of untrusted input in the 'rest_simpleTranscribeAudio' and 'rest_simpleVisionQuery' functions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

Executive Summary

This vulnerability is a PHP Object Injection via PHAR Deserialization in the AI Engine plugin for WordPress versions up to 3.1.8. It occurs in the 'rest_simpleTranscribeAudio' and 'rest_simpleVisionQuery' functions, allowing authenticated users with Subscriber-level access or higher to inject a PHP object. However, it only has an impact if another plugin or theme with a POP (Property Oriented Programming) chain is installed, which could then enable actions like deleting files, retrieving sensitive data, or executing code.

Impact Analysis

If the vulnerable plugin is used alongside another plugin or theme containing a POP chain, an attacker with Subscriber-level access could exploit this vulnerability to delete arbitrary files, retrieve sensitive data, or execute arbitrary code on the affected WordPress site.

Mitigation Strategies

To mitigate this vulnerability, immediately update the AI Engine plugin for WordPress to a version later than 3.1.8 where the issue is fixed. Additionally, review and remove any plugins or themes that may contain POP chains which could be exploited in conjunction with this vulnerability. Limit Subscriber-level access and above to trusted users only, and monitor for unusual activity related to the 'rest_simpleTranscribeAudio' and 'rest_simpleVisionQuery' functions.
