Advisory
Source description from Wordfence Intelligence, credited to John Ryan Albon.
The Booster for WooCommerce – PDF Invoices, Abandoned Cart, Variation Swatches & 100+ Tools plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 8.4.0. This is due to deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. 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.
