What the vulnerability does
01Description
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.
Explanation of Vulnerability in Simple Terms
02Summary
WP Easy Post Types versions 1.4.4 and earlier contain a deserialization vulnerability that allows authenticated users to execute arbitrary code on the site. An attacker with low-level access can craft malicious serialized data that, when processed by the plugin, runs their own PHP code with full site privileges. This affects confidentiality, integrity, and availability of the WordPress installation.
