CVE-2026-28105 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the ThemeREX Good Energy (goodenergy) WordPress theme, enabling Object Injection. The issue affects Good Energy versions from n/a through 1.7.7, as published on 2026-03-05.
With 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), the vulnerability can be exploited by unauthenticated remote attackers requiring low complexity and no user interaction. Exploitation allows high-impact compromise of confidentiality, integrity, and availability through object injection.
The Patchstack advisory (https://patchstack.com/database/Wordpress/Theme/goodenergy/vulnerability/wordpress-good-energy-theme-1-7-7-php-object-injection-vulnerability?_s_id=cve) details the PHP object injection vulnerability in Good Energy theme version 1.7.7, recommending mitigation via updating to a non-vulnerable version beyond 1.7.7.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
