CVE-2026-18080
CriticalCVSS 9.8Summary
The ERP: Complete HR, Accounting & CRM Suite Built for WooCommerce plugin for WordPress (up to version 1.17.8) is vulnerable to unrestricted file upload via the save_attachments() function. Missing file extension validation and path normalization allow unauthenticated attackers to write malicious PHP outside the .htaccess-protected directory, potentially leading to remote code execution if PHP executes in uploads.
Risk Assessment
Potential for remote code execution on the WordPress server, leading to full site and data compromise.
Recommendation
Update the plugin to the latest version, or if not possible, disable the CRM module and IMAP Email Connect feature or restrict PHP execution in the uploads directory.
Original NVD description (English source)
The ERP: Complete HR, Accounting & CRM Suite Built for WooCommerce plugin for WordPress is vulnerable to Unrestricted File Type Upload in all versions up to, and including, 1.17.8 via the save_attachments() function. This is due to missing file extension validation and missing path normalization when CRM Email Connect processes inbound IMAP email attachments. This makes it possible for unauthenticated attackers to send a crafted email to the site's configured inbound mailbox with a forged References header matching the plugin's expected pattern and an attachment filename such as `../helper.php`, causing the cron-based IMAP sync job to write attacker-controlled PHP outside of the .htaccess-protected `crm-attachments` directory and into `wp-content/uploads/`. On configurations where PHP executes in uploads, this can lead to remote code execution. Exploitation requires the CRM module and IMAP Email Connect feature to be enabled and configured.
