AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network email delivery (AV:N/PR:N/UI:N), but forging the References header and requiring PHP-executable uploads raises complexity to AC:H; full RCE gives C/I/A:H.

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.

Unrestricted file upload in the wedevs WP ERP plugin (ERP: Complete HR, Accounting & CRM Suite for WooCommerce) for WordPress, in all versions through 1.17.8, allows unauthenticated attackers to write attacker-controlled PHP into wp-content/uploads/ via the save_attachments() function when the CRM IMAP Email Connect feature parses inbound email attachments. Because file extension validation and path normalization are both missing, a crafted email with a forged References header and a path-traversal filename escapes the .htaccess-protected crm-attachments directory, enabling remote code execution on hosts where PHP executes in the uploads directory. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the WP ERP CRM module AND the IMAP Email Connect (inbound email sync) feature to be enabled and configured with a reachable mailbox - this is not a default WordPress or default-plugin state. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H scores 9.8 and describes a network-reachable, low-complexity, unauthenticated path with full confidentiality, integrity, and availability impact, which is consistent with the described attack: an attacker merely emails the site's configured inbound mailbox. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upstream fix available (PR/commit); released patched version not independently confirmed - the code change is committed in WordPress plugin changeset 3656848 (https://plugins.trac.wordpress.org/changeset/3656848/erp), so update WP ERP to the latest available release above 1.17.8 as soon as the vendor publishes it and verify via the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/b9d11eb9-5e18-459f-a9d4-cccb1d593402?source=cve). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all WordPress instances to confirm whether the wedevs WP ERP plugin version 1.17.8 or earlier is installed and the CRM IMAP Email Connect feature is active; if present, immediately configure Web Application Firewall rules to block requests to the save_attachments() function and implement email-level restrictions on inbound attachments. …
