Technical details

A PHP Object Injection vulnerability exists in the JetEngine plugin for WordPress due to the insecure deserialization of user-supplied data. An unauthenticated remote attacker can exploit this by sending specially crafted input to the application. If a suitable Property-Oriented Programming (POP) chain is present on the server, the attacker can achieve remote code execution, SQL injection, or file system traversal. The vulnerability is fixed in version 3.8.10.1.
