Technical details

A PHP Object Injection vulnerability exists in the Valeska theme for WordPress (versions <= 1.2.2) due to improper deserialization of user-supplied data (CWE-502). An unauthenticated remote attacker can exploit this by sending specially crafted input to a vulnerable component of the theme. If a suitable Property-Oriented Programming (POP) chain is present in the environment, the attacker could achieve remote code execution, perform SQL injection, or access sensitive files. The vulnerability is mitigated in version 1.3.
