CVE-2026-1426 describes a PHP Object Injection vulnerability in the Advanced AJAX Product Filters WordPress plugin, affecting all versions up to 3.1.9.6, specifically within its Live Composer compatibility layer. This flaw allows authenticated attackers with Author-level access or higher to inject a PHP Object. The vulnerability has a high CVSS score of 8.8, indicating a significant risk for potential data compromise, integrity issues, and availability impact, but it requires the Live Composer plugin to also be active. While no known POP chain exists within the vulnerable plugin itself, if another plugin or theme on the system provides one, it could lead to severe consequences like arbitrary file deletion, sensitive data retrieval, or code execution. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
