Structured Content < 1.6 - Contributor+ PHP Object Injection

Description The plugin is vulnerable to PHP Object Injection via deserialization of untrusted input. This makes it possible for attackers, with contributor-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 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.
