CVE-2026-2020 describes a PHP Object Injection vulnerability in all versions up to and including 6.1.7 of the JS Archive List plugin for WordPress. This flaw, rated High severity (CVSS 7.5), allows authenticated attackers with Contributor-level access or higher to inject PHP Objects through the 'included' shortcode attribute due to deserialization of untrusted input. While no direct POP chain exists within the plugin, if another installed plugin or theme provides one, an attacker could potentially achieve arbitrary file deletion, sensitive data retrieval, or code execution. There is currently no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV listing, though it has garnered some community discussion.
