The vulnerability identified as CVE-2025-63077 affects the HappyMonster Happy Addons plugin for Elementor, a widely used WordPress plugin that extends the Elementor page builder with additional widgets and features. The core issue is a Missing Authorization vulnerability, meaning that certain functionalities or endpoints within the plugin do not properly verify whether a user has the necessary permissions to perform specific actions. This misconfiguration in access control allows attackers, potentially unauthenticated or with limited privileges, to exploit the plugin to execute unauthorized operations. These could include modifying site content, altering plugin settings, or accessing sensitive data managed by the plugin. The affected versions include all versions up to and including 3.20.2, with no lower bound specified. The vulnerability was reserved in late October 2025 and published in December 2025, with no known exploits in the wild at the time of disclosure. No CVSS score has been assigned, indicating that the vulnerability is newly disclosed and may require further analysis. The absence of authentication requirements for exploitation increases the risk profile. Since Happy Addons is popular among WordPress users, especially for enhancing Elementor, the vulnerability could have a broad impact on websites relying on this plugin for their content management and presentation layers.

For European organizations, the impact of CVE-2025-63077 can be significant, especially for those relying on WordPress sites enhanced by the Happy Addons plugin. Unauthorized access due to missing authorization checks can lead to website defacement, unauthorized content changes, data leakage, or even the insertion of malicious code. This can damage brand reputation, lead to compliance violations (especially under GDPR if personal data is exposed), and disrupt business operations. Organizations in sectors such as e-commerce, media, education, and government that use WordPress extensively are at higher risk. The ease of exploitation without authentication means attackers can target vulnerable sites en masse, increasing the likelihood of widespread compromise. Additionally, compromised sites can be used as platforms for further attacks, including phishing or malware distribution, amplifying the threat. The lack of a patch at the time of disclosure necessitates immediate risk management and monitoring to prevent exploitation.

1. Immediate action should include auditing all WordPress sites for the presence of the Happy Addons plugin and identifying versions in use. 2. Monitor official vendor channels and security advisories for the release of a patch or updated plugin version that addresses the missing authorization issue. 3. Until a patch is available, restrict access to WordPress admin areas and plugin endpoints using web application firewalls (WAFs) or access control lists (ACLs) to limit exposure. 4. Implement strict user role management and minimize the number of users with administrative privileges to reduce potential attack vectors. 5. Enable detailed logging and monitoring of plugin-related activities to detect suspicious behavior indicative of exploitation attempts. 6. Consider temporarily disabling the Happy Addons plugin if it is not critical to site functionality. 7. Educate site administrators about the vulnerability and the importance of timely updates. 8. Conduct regular backups of website data and configurations to enable rapid recovery in case of compromise. 9. Employ security plugins that can detect unauthorized changes or access attempts related to plugins. 10. Review and harden overall WordPress security posture, including keeping core, themes, and other plugins up to date.
