【中文导读】WP Easy Post Types 存在反序列化风险（高危风险）。具体受影响版本、触发条件和修复方案以 NVD/厂商公告为准。 【原始描述】The WP Easy Post Types plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.4.4 via deserialization of untrusted input from the 'text' parameter in the 'ajax_import_content' function. This allows authenticated attackers, with subscriber-level permissions and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
