CVE-2026-2375: Appcheap App Builder – Create Native Android & IOS Apps On The Flight

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

The App Builder – Create Native Android & iOS Apps On The Flight plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.5.10. This is due to the `verify_role()` function in `AuthTrails.php` explicitly whitelisting the `wcfm_vendor` role alongside `subscriber` and `customer`, and assigning it directly via `wp_insert_user()` without integrating with WCFM Marketplace's vendor approval workflow. This makes it possible for unauthenticated attackers to register an account with the `wcfm_vendor` role by supplying the `role` parameter in the `/wp-json/app-builder/v1/register` REST API endpoint, bypassing the standard WCFM vendor approval process and immediately gaining vendor-level privileges (product management, order access, store management) on sites where WCFM Marketplace is active.
