Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Timely flaw remediation requires patching the vulnerable ModelTheme Addons plugin to version 1.5.6 or later, directly eliminating the deserialization vulnerability.
Information input validation ensures untrusted data is checked before deserialization, preventing PHP object injection exploitation.
Vulnerability scanning identifies the CVE-2025-68531 deserialization flaw in the plugin, enabling prompt remediation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
PHP object injection via untrusted deserialization directly enables remote code execution on a publicly accessible WordPress application (authenticated but low-privilege).

Deeper analysisAI
CVE-2025-68531 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the ModelTheme Addons for WPBakery and Elementor plugin (modeltheme-addons-for-wpbakery) for WordPress. It enables PHP Object Injection by allowing untrusted data to be deserialized. The vulnerability affects all versions of the plugin from its initial release through versions prior to 1.5.6. It carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
An attacker with low-privilege authenticated access (PR:L) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) and no user interaction required (UI:N). Successful exploitation could lead to high confidentiality, integrity, and availability impacts (C:H/I:H/A:H), potentially allowing arbitrary code execution, data manipulation, or denial of service on the affected WordPress site.
Patchstack advisories recommend updating the ModelTheme Addons for WPBakery and Elementor plugin to version 1.5.6 or later, which addresses the object injection vulnerability.
