WooCommerce Product Add-ons < 6.2.0 - Shop Manager+ PHP Object Injection

Description

The plugin is vulnerable to PHP Object Injection in versions up to, and including, 6.1.3 via deserialization of untrusted input. This allows authenticated attackers, with shop manager permissions and above, to inject a PHP Object. It is unknown if a POP chain is also present in the 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.
