CVE-2025-63053 is an authorization bypass vulnerability classified under CWE-639, found in the Jewel Theme Master Addons for Elementor plugin, a popular WordPress extension used to enhance Elementor page builder functionality. The vulnerability stems from incorrect access control implementation where a user-controlled key parameter is used to determine authorization levels. This misconfiguration allows an attacker to bypass intended access restrictions without requiring authentication or user interaction, potentially exposing sensitive information or restricted functionality. The affected versions include all releases up to 2.0.9.9.4, with no specific earliest affected version identified. The vulnerability was reserved on October 24, 2025, and published on December 31, 2025. The CVSS v3.1 base score is 5.3 (medium), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating remote network exploitation with low attack complexity, no privileges or user interaction needed, and limited confidentiality impact. No patches or known exploits are currently available, but the issue poses a risk of unauthorized data access due to flawed access control logic. The vulnerability affects the confidentiality of data but does not impact integrity or availability. Since the plugin is widely used in WordPress environments, especially in sites leveraging Elementor, the risk is significant for web properties relying on this plugin for content management and presentation.

For European organizations, this vulnerability could lead to unauthorized access to sensitive or restricted content managed through the Master Addons for Elementor plugin. This may result in data leakage, exposure of internal information, or unauthorized use of site features, potentially damaging reputation and compliance posture, especially under GDPR regulations. Since the exploit requires no authentication or user interaction, attackers can remotely target vulnerable sites at scale. Organizations relying heavily on WordPress and Elementor for their web presence, including e-commerce, corporate, and governmental sites, are at risk. The impact is primarily on confidentiality, with no direct effect on data integrity or service availability. However, unauthorized access could facilitate further attacks or data harvesting. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge post-disclosure. The vulnerability's medium severity suggests it should be addressed promptly but is not critical unless combined with other weaknesses.

1. Monitor the vendor’s official channels for patches addressing CVE-2025-63053 and apply updates immediately upon release. 2. Until patches are available, implement web application firewall (WAF) rules to detect and block suspicious requests containing unusual or unexpected key parameters related to the plugin. 3. Conduct a thorough review of access control configurations within the Master Addons plugin settings and restrict access to sensitive features only to trusted users. 4. Employ strict input validation and sanitization on user-supplied parameters to prevent manipulation of authorization keys. 5. Enable detailed logging and monitoring of access to the plugin’s functionality to detect potential exploitation attempts early. 6. Limit exposure of the WordPress admin and plugin endpoints by IP whitelisting or VPN access where feasible. 7. Educate site administrators about the risks of unauthorized access and encourage regular security audits of WordPress plugins and themes. 8. Consider deploying intrusion detection systems (IDS) tailored to WordPress environments to identify anomalous behavior related to this vulnerability.
