Summary
The Sunshine Photo Cart plugin for WordPress is affected in all versions through 3.7.4. It deserializes untrusted input (CWE-502), which lets an unauthenticated remote attacker inject a PHP object. The sources state that the plugin contains no known POP chain, so impact depends on another installed plugin or theme that provides one, which could allow deleting arbitrary files, retrieving sensitive data or executing code.

Description from the CNA
The Sunshine Photo Cart – Client Photo Gallery & Photo Proofing for Photographers plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.7.4 via 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, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. If a POP chain is present via an additional plugin or theme installed on the target system, the attacker can store the malicious payload unauthenticated via the public favorites page and trigger deserialization by viewing any image in a non-viewable or private gallery.
