CVE-2025-63053 is an authorization bypass vulnerability identified in the Master Addons for Elementor plugin developed by Jewel Theme, affecting all versions up to 2.0.9.9.4. The vulnerability is categorized under CWE-639, which pertains to authorization bypass through user-controlled keys. This means that the plugin improperly validates access control by relying on keys or parameters that can be manipulated by an attacker, allowing unauthorized access to restricted functionalities or data. The vulnerability is exploitable remotely without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The CVSS base score of 5.3 reflects a medium severity level, primarily due to its limited impact on confidentiality and no impact on integrity or availability. The flaw arises from incorrectly configured access control security levels within the plugin's code, which fails to enforce proper authorization checks on sensitive operations. Although no known exploits are currently active in the wild, the vulnerability poses a risk to websites using this plugin, particularly those that expose sensitive or proprietary information through the affected features. The lack of available patches necessitates immediate attention from administrators to apply compensating controls. Given the widespread use of Elementor and its addons in WordPress sites, this vulnerability could be leveraged to gain unauthorized access to site components, potentially leading to data leakage or further exploitation if combined with other vulnerabilities.

For European organizations, the impact of CVE-2025-63053 can vary depending on their reliance on WordPress sites using the Master Addons for Elementor plugin. Organizations in sectors such as e-commerce, media, and government that use this plugin to enhance website functionality may face unauthorized access to restricted content or administrative features. Although the confidentiality impact is limited, unauthorized access could expose sensitive customer data, internal content, or configuration details, potentially leading to reputational damage and regulatory compliance issues under GDPR. The vulnerability does not affect integrity or availability directly, but attackers could use the bypass as a stepping stone for further attacks. Since exploitation requires no authentication or user interaction, the attack surface is broad, increasing risk. European organizations with public-facing websites are particularly vulnerable, as the flaw can be exploited remotely over the internet. The absence of known exploits in the wild currently reduces immediate risk, but the medium severity score warrants proactive mitigation to prevent future exploitation.

1. Monitor official Jewel Theme and Master Addons for Elementor channels for security updates or patches and apply them promptly once available. 2. Until a patch is released, restrict access to the affected plugin’s functionalities by limiting user roles and permissions within WordPress to only trusted administrators. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests that attempt to manipulate user-controlled keys or access restricted endpoints related to the plugin. 4. Conduct regular security audits and penetration testing focused on WordPress plugins to identify and remediate similar authorization issues. 5. Employ network-level access controls to limit exposure of administrative interfaces and sensitive endpoints to trusted IP ranges where feasible. 6. Educate site administrators about the risks of installing third-party plugins and encourage minimal plugin usage to reduce attack surface. 7. Maintain comprehensive backups and incident response plans to quickly recover in case of compromise. 8. Consider temporary disabling or removing the Master Addons plugin if it is not critical to website operations until a fix is available.
