CVE-2026-57719 Overview
CVE-2026-57719 is an unrestricted file upload vulnerability in the CodeRevolution Aimogen Pro WordPress plugin. The flaw affects all versions of aimogen-pro up to and including 2.8.3. Attackers can upload files with dangerous types to the WordPress server without proper validation. The issue is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). Successful exploitation grants remote code execution on the underlying web server, leading to full site compromise.
Critical Impact
Unauthenticated attackers can upload malicious files remotely over the network, achieving arbitrary code execution with a scope change that impacts resources beyond the vulnerable component.
Affected Products
- CodeRevolution Aimogen Pro (aimogen-pro) WordPress plugin
- All versions from initial release through 2.8.3
- WordPress installations with the Aimogen Pro plugin activated

Technical Details for CVE-2026-57719
Vulnerability Analysis
The Aimogen Pro plugin exposes a file upload handler that fails to validate the type, extension, or MIME content of uploaded files. An attacker submits an HTTP request containing a PHP file or other executable content. The plugin writes the file to a web-accessible directory without sanitization. The attacker then requests the uploaded file directly, causing the PHP interpreter to execute the embedded payload.
The vulnerability requires no authentication and no user interaction. The attack scope is changed, meaning the compromise extends beyond the plugin to the WordPress site, database credentials stored in wp-config.php, and other tenants on shared hosting environments.
Root Cause
The plugin lacks a server-side allowlist of permitted file extensions and MIME types. It also fails to enforce authentication checks on the upload endpoint. WordPress functions such as wp_check_filetype() and capability checks like current_user_can('upload_files') are either missing or bypassable in the vulnerable code path.
Attack Vector
Remote attackers send a crafted multipart HTTP POST request to the plugin's upload endpoint. The request includes a PHP web shell disguised with any extension the server executes. Once uploaded, the attacker accesses the file via its public URL and issues commands through the shell. See the Patchstack Vulnerability Advisory for additional technical context.
Detection Methods for CVE-2026-57719
Indicators of Compromise
- Unexpected .php, .phtml, or .phar files present in wp-content/uploads/ or plugin-specific upload directories
- HTTP POST requests to Aimogen Pro upload endpoints originating from unauthenticated sessions
- Outbound network connections from the web server process (php-fpm, apache2, www-data) to unfamiliar hosts
- New administrative WordPress users or modified wp_options entries created shortly after suspicious uploads
Detection Strategies
- Scan the WordPress uploads directory for files with executable extensions using periodic filesystem integrity checks
- Inspect web server access logs for POST requests to plugin endpoints followed by GET requests to newly created files
- Deploy web application firewall rules that block uploads containing PHP tags or shell functions such as eval, system, and passthru
Monitoring Recommendations
- Alert on webserver processes spawning shells (sh, bash, cmd.exe) or reconnaissance tools
- Monitor file creation events in web-accessible directories and correlate with the requesting IP address
- Track WordPress plugin inventory to identify hosts running aimogen-pro version 2.8.3 or earlier
How to Mitigate CVE-2026-57719
Immediate Actions Required
- Deactivate and remove the Aimogen Pro plugin until a patched release is confirmed available
- Audit wp-content/uploads/ and any plugin-controlled directories for unauthorized files, then remove them
- Rotate WordPress administrator credentials, secret keys in wp-config.php, and any API tokens accessible from the web server
Patch Information
At time of publication, the Patchstack advisory lists all versions through 2.8.3 as affected. Administrators should monitor the vendor and Patchstack advisory for a fixed release and apply it immediately once available.
Workarounds
- Block execution of PHP files inside the wp-content/uploads/ directory using web server configuration
- Restrict access to the plugin's upload endpoint at the reverse proxy or WAF layer until a patch is applied
- Enforce virtual patching rules that reject multipart uploads containing PHP tags or executable MIME types
# Apache: prevent PHP execution in the uploads directory
<Directory "/var/www/html/wp-content/uploads">
<FilesMatch "\.(php|phtml|phar|php[0-9]+)$">
Require all denied
</FilesMatch>
</Directory>
# Nginx equivalent
location ~* /wp-content/uploads/.*\.(php|phtml|phar)$ {
deny all;
return 403;
}
