Deeper analysis
CVE-2025-60226 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the White Rabbit WordPress theme developed by axiomthemes, enabling PHP Object Injection. The issue affects all versions of the White Rabbit theme up to and including 1.5.2. Published on 2025-10-22, it has a CVSS v3.1 base score of 9.8, indicating critical severity due to its network accessibility, low attack complexity, lack of required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
A remote unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction. Successful exploitation allows object injection, potentially leading to arbitrary code execution, data manipulation, or denial of service, depending on the injected objects and server configuration.
