CVE-2025-63077 is a missing authorization vulnerability identified in the HappyMonster Happy Addons plugin for Elementor, a popular WordPress page builder extension. The vulnerability arises from incorrectly configured access control security levels, allowing an attacker with some level of privileges (PR:L) to access or perform actions that should be restricted. The flaw affects all versions up to and including 3.20.2. The CVSS 3.1 base score is 4.3, indicating a medium severity, with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N. This means the attack can be performed remotely over the network with low attack complexity, requires privileges but no user interaction, and impacts confidentiality only, without affecting integrity or availability. The vulnerability could allow an attacker to access sensitive data or functionality that should be protected by authorization checks, potentially leading to information disclosure. No known exploits have been reported in the wild, and no patches or fixes are currently linked, suggesting that organizations should monitor for updates. The issue was reserved in late October 2025 and published in December 2025. The vulnerability is specific to the Happy Addons for Elementor plugin, which extends Elementor's capabilities with additional widgets and features, widely used in WordPress sites for enhanced design and functionality.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of data managed through WordPress sites using the Happy Addons plugin. Unauthorized access could lead to exposure of sensitive information, potentially including customer data, internal content, or configuration details. While the vulnerability does not affect integrity or availability, the confidentiality breach could undermine trust and compliance with data protection regulations such as GDPR. Organizations relying heavily on WordPress for their web presence, marketing, or e-commerce may face reputational damage and legal consequences if sensitive data is exposed. The requirement for some privilege level reduces the risk somewhat, but insider threats or compromised accounts could exploit this flaw. The absence of known exploits in the wild currently limits immediate impact, but proactive mitigation is essential to prevent future exploitation.

European organizations should take the following specific steps: 1) Monitor official HappyMonster and WordPress plugin repositories for patches addressing CVE-2025-63077 and apply updates immediately upon release. 2) Conduct a thorough audit of user roles and permissions within WordPress to ensure the principle of least privilege is enforced, minimizing the number of users with elevated privileges. 3) Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the Happy Addons plugin endpoints. 4) Regularly review access logs for unusual activity that could indicate attempts to exploit authorization weaknesses. 5) Consider temporarily disabling or limiting the use of the Happy Addons plugin if patching is delayed and the risk is deemed significant. 6) Educate administrators and content managers about the risks of privilege misuse and encourage strong authentication practices, including multi-factor authentication (MFA). 7) Integrate vulnerability scanning tools that specifically check for plugin vulnerabilities in WordPress environments to maintain continuous security posture.
