Technical details
A PHP Object Injection vulnerability exists in the Reina theme for WordPress in versions up to and including 2.1. The flaw stems from the insecure deserialization of user-supplied data (CWE-502), which allows an unauthenticated attacker to inject PHP objects. If a suitable Property-Oriented Programming (POP) chain is present within the environment, this can lead to remote code execution, SQL injection, or unauthorized file access. The attack can be carried out over the network without any user interaction, though the CVSS vector indicates high complexity, likely due to the requirement of a specific POP chain to achieve full impact. A patch is available in version 2.2.
Affected products
