CVE-2026-6451: 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.
The exploitability of CVE-2026-6451 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2026-6451 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-6451, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-6451, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
