What is CVE-2026-2375?
CVE-2026-2375 is a medium-severity vulnerability in appcheap App Builder – Create Native Android & iOS Apps On The Flight, published on 21 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-269
