CVE-2026-2375Network attack vector

Unauthenticated vendor-account creation via unchecked role parameter

Published Mar 21, 2026 · Updated Mar 21, 2026

Privilege escalation in Appcheap App Builder 5.5.10 and earlier allows remote attackers to create vendor-level WordPress accounts. AuthTrails.php's verify_role() accepts the attacker-controlled wcfm_vendor role and passes it to wp_insert_user() without WCFM Marketplace approval. Sites are exposed only when registration and WCFM Marketplace are active; successful requests grant product, order, and store-management access.
