 "title": "SureCart – Ecommerce Made Easy For Selling Physical Products, Digital Downloads, Subscriptions, Donations, & Payments <= 4.9.3 - Authenticated (Shop Worker+) PHP Object Injection via Integrations REST API",
 "description": "The SureCart plugin for WordPress is vulnerable to PHP Object Injection via the integrations REST API endpoint (/surecart/v1/integrations) in all versions up to, and including, 4.9.3, due to deserialization of untrusted input when local database models fill their attributes. Every attribute value was passed through maybe_unserialize() twice without restricting allowed classes, and request parameters such as 'integration_id', 'price_id' and 'variant_id' are passed to the model unchanged. This makes it possible for authenticated attackers with SureCart Shop Worker-level access and above to inject a PHP object. No known POP chain is present in the vulnerable plugin. If a POP chain is present via another plugin or theme installed on the target system, it may allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.",
