Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at wordfence.com. The identification of this vulnerability is CVE-2026-18080 since 07/28/2026. The exploitation is known to be easy. The attack may be initiated remotely.
