E2Pdf < 1.20.19 - Authenticated (Administrator+) PHP Object Injection

Description

The E2Pdf plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.20.18 via deserialization of untrusted input within the import_action and ajax_upload functions. This makes it possible for authenticated attackers, with administrative-level access and above, to inject a PHP Object. 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.
