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.","severity":{"version":"3.1","score":9.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"critical","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00869,"percentile":0.5908,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":true,"fix_available":false},"cwes":["CWE-434"],"published":"2026-08-26T11:05:44Z","modified":"2026-08-26T18:32:04Z","exploits":[{"source":"pocgithub","id":"Polosss/By-Poloss..-..CVE-2026-18080","title":"Polosss/By-Poloss..-..CVE-2026-18080","date":"2026-08-26","url":"https://github.com/Polosss/By-Poloss..-..CVE-2026-18080"}],"products":[{"vendor":"wedevs","product":"erp: complete hr, accounting \u0026 crm suite built for woocommerce"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b9d11eb9-5e18-459f-a9d4-cccb1d593402?source=cve"},{"url":"https://plugins.trac.wordpress.org/changeset/3656848/erp"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-18080"},{"url":"https://github.com/advisories/GHSA-xp5r-phw6-jcr2"}],"sources":{"cve":[{"id":"CVE-2026-18080","title":"ERP: Complete HR, Accounting \u0026 CRM Suite Built for WooCommerce \u003c= 1.17.8 - Unauthenticated Arbitrary File Upload via CRM Email Connect IMAP Attachment","description":"The ERP: Complete HR, Accounting \u0026 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.
