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.

CVE-2026-18080 affects the ERP: Complete HR, Accounting & CRM Suite Built for WooCommerce WordPress plugin in all versions up to and including 1.17.8. The vulnerability exists in the save_attachments() function, which lacks file extension validation and path normalization when processing inbound IMAP email attachments via the CRM Email Connect feature. Unauthenticated attackers can send a crafted email with a forged References header and a path-traversal attachment filename (e.g., '../helper.php') to the site's configured inbound mailbox. The cron-based IMAP sync job then writes attacker-controlled PHP files outside the protected 'crm-attachments' directory into 'wp-content/uploads/'. On servers where PHP execution is permitted in the uploads directory, this can result in remote code execution. Exploitation requires the CRM module and IMAP Email Connect feature to be enabled and configured. A patch is available via the plugin's changeset 3656848.
