FKIE_CVE-2026-6451
Vulnerability from fkie_nvd - Published: 2026-04-17 08:16 - Updated: 2026-04-22 20:22
Severity ?
Summary
The cms-fuer-motorrad-werkstaetten plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.0.0. This is due to missing nonce validation on all eight AJAX deletion handlers: vehicles_cfmw_d_vehicle, contacts_cfmw_d_contact, suppliers_cfmw_d_supplier, receipts_cfmw_d_receipt, positions_cfmw_d_position, catalogs_cfmw_d_article, stock_cfmw_d_item, and settings_cfmw_d_catalog. None of these handlers call check_ajax_referer() or wp_verify_nonce(), nor do they perform any capability checks via current_user_can(). This makes it possible for unauthenticated attackers to delete arbitrary vehicles, contacts, suppliers, receipts, positions, catalog articles, stock items, or entire supplier catalogs via a forged request, provided they can trick a logged-in user into performing an action such as clicking a link to a malicious page.
