Deeper analysisAI
CVE-2025-60233 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Themeton Zuut WordPress theme, which allows Object Injection. This issue affects Zuut versions from n/a through 1.4.2. Published on 2026-03-19, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its potential for severe impact.
An unauthenticated remote attacker can exploit this vulnerability over the network with low attack complexity and without requiring user interaction. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary code execution or other severe outcomes via malicious object injection during deserialization.
Mitigation details are provided in the Patchstack advisory at https://patchstack.com/database/Wordpress/Theme/zuut/vulnerability/wordpress-zuut-theme-1-4-2-php-object-injection-vulnerability?_s_id=cve, which covers the PHP Object Injection vulnerability in the Zuut theme up to version 1.4.2.
