## Technical details

A PHP Object Injection vulnerability exists in the Santé theme for WordPress (versions <= 1.5.1) due to improper deserialization of untrusted data (CWE-502). An unauthenticated remote attacker can exploit this by submitting specially crafted input to a vulnerable component. If a suitable Property-Oriented Programming (POP) chain is present on the server, the attacker can achieve remote code execution, perform SQL injection, or conduct path traversal. The vulnerability is mitigated in version 1.6. Although the attack vector is network-based and requires no privileges, the CVSS complexity is rated as high, likely due to the requirement of a valid POP chain for full exploitation.
