Deeper analysis

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.
