CVE-2026-1400: CWE-434 Unrestricted Upload of File with Dangerous Type in tigroumeow AI Engine – The Chatbot, AI Framework & MCP for WordPress
The AI Engine – The Chatbot and AI Framework for WordPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the `rest_helpers_update_media_metadata` function in all versions up to, and including, 3.3.2. This makes it possible for authenticated attackers, with Editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The attacker can upload a benign image file, then use the `update_media_metadata` endpoint to rename it to a PHP file, creating an executable PHP file in the uploads directory.
AI Analysis
Technical Summary
The AI Engine – The Chatbot and AI Framework for WordPress plugin suffers from an unrestricted file upload vulnerability (CWE-434) in the rest_helpers_update_media_metadata function. Authenticated users with Editor-level access or higher can bypass file type validation, upload arbitrary files, and rename them to executable PHP files within the uploads directory. This flaw can lead to remote code execution on the server hosting the WordPress site. The issue affects all plugin versions up to 3.3.2. There is no vendor-provided patch or advisory detailing remediation at this time.
Potential Impact
Successful exploitation allows an authenticated attacker with Editor or higher privileges to upload and execute arbitrary PHP code on the server, potentially leading to full server compromise. This impacts confidentiality, integrity, and availability of the affected WordPress site and its underlying server environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Editor-level access to trusted users only and consider disabling or limiting the use of the vulnerable plugin. Monitor for updates from the vendor and apply patches promptly once released.
