What the vulnerability does
01Description
The WooCommerce Infinite Scroll and Ajax Pagination plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.8 via the 'settings' parameter in the 'import_settings' function. This is due to deserialization of untrusted data supplied via the import configuration feature without capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. No POP chain is present within the vulnerable plugin itself, but if a POP chain is present via an additional plugin or theme installed on the target system, it could allow an attacker to delete arbitrary files, retrieve sensitive data, or execute code.

An authenticated attacker with low privileges can send a specially crafted request to deserialize untrusted data, leading to remote code execution on the site. This allows the attacker to read sensitive data, modify site content, or disable the site entirely.
