CVE-2022-4939 is a critical privilege escalation vulnerability affecting the WCFM Membership plugin for WordPress, versions up to and including 2.10.0. It stems from a missing capability check in the wp_ajax_nopriv_wcfm_ajax_controller AJAX action, allowing unauthenticated attackers to manipulate membership registration settings. This enables attackers to register as any user role, including administrators, leading to full system compromise. The vulnerability has a CVSS score of 9.8 (Critical) due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is it listed on the KEV catalog, indicating no active exploitation. Community discussion and media coverage are also minimal.
