Advisory
Source description from Wordfence Intelligence, credited to Ananda Dhakal.
The SureCart – Ecommerce Made Easy For Selling Physical Products, Digital Downloads, Subscriptions, Donations, & Payments plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.9.3. This is due to deserialization of untrusted input. This makes it possible for authenticated attackers, with custom role-level access and above, 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.
