Technical Details for CVE-2025-6325

Vulnerability Analysis

This vulnerability stems from an Incorrect Privilege Assignment flaw (CWE-266) in the King Addons for Elementor WordPress plugin. The vulnerability allows attackers to bypass intended access controls and escalate privileges without requiring authentication. Due to the network-accessible nature of WordPress installations and the lack of authentication requirements, attackers can exploit this vulnerability remotely with minimal complexity.

The impact of successful exploitation is severe, affecting confidentiality, integrity, and availability of the affected WordPress site. An attacker who successfully exploits this vulnerability could gain administrative access, modify site content, inject malicious code, steal sensitive data, or completely take over the compromised website.

Root Cause

The root cause of CVE-2025-6325 lies in improper privilege assignment within the King Addons for Elementor plugin. CWE-266 (Incorrect Privilege Assignment) occurs when a product incorrectly assigns privileges to a user, creating an unintended sphere of control. In this case, the plugin fails to properly validate and enforce privilege boundaries, allowing users to obtain elevated permissions they should not possess.

Attack Vector

The attack vector for this vulnerability is network-based, meaning attackers can exploit it remotely over the internet without physical access to the target system. The exploitation requires no user interaction and can be performed without any prior authentication to the WordPress site. An attacker would target the vulnerable King Addons for Elementor plugin functionality that fails to properly validate privilege assignments, ultimately escalating their access level on the WordPress installation.

Detection Methods for CVE-2025-6325

Indicators of Compromise
