CVE-2025-64283 is an authorization bypass vulnerability found in the RTMKit plugin developed by Rometheme for the Elementor page builder on WordPress. The vulnerability stems from incorrectly configured access control security levels, specifically allowing an attacker to manipulate a user-controlled key to bypass authorization checks. This flaw enables an attacker with limited privileges (PR:L) to gain unauthorized access to sensitive information or functionality that should be restricted. The vulnerability affects all RTMKit versions up to and including 1.6.7. The CVSS 3.1 base score of 6.5 reflects a medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). This means that an attacker with some level of authenticated access can exploit the vulnerability remotely without requiring user interaction to access confidential data. No known exploits have been reported in the wild, and no official patches have been released yet. The vulnerability is significant because it undermines the access control mechanisms that protect sensitive data or administrative functions within the RTMKit plugin, potentially leading to data leakage or unauthorized configuration changes. Since RTMKit is a plugin for Elementor, a widely used WordPress page builder, the vulnerability could affect numerous websites that rely on this plugin for theme and page management. The exploitability is relatively straightforward due to low attack complexity and no user interaction requirement, but it does require some level of privilege, limiting exposure to authenticated users or compromised accounts.

For European organizations, the primary impact of CVE-2025-64283 is the potential unauthorized disclosure of sensitive information managed by the RTMKit plugin within WordPress environments. This could include access to configuration data, user information, or other confidential content protected by the plugin's access controls. The vulnerability does not directly impact data integrity or availability but compromises confidentiality, which can lead to further attacks such as privilege escalation or lateral movement within the network. Organizations relying on RTMKit for their website themes or page management may face reputational damage, regulatory compliance issues (especially under GDPR), and potential financial losses if sensitive customer or business data is exposed. Since the attack requires some level of privileges, the risk is higher in environments where user accounts are not tightly controlled or where credential compromise is possible. The lack of patches at disclosure means organizations must rely on interim mitigations to reduce risk. Given the widespread use of WordPress and Elementor in Europe, especially among SMEs and enterprises with online presence, this vulnerability could have broad implications if exploited at scale.

1. Monitor Rometheme's official channels and security advisories closely for the release of a patch addressing CVE-2025-64283 and apply updates promptly once available. 2. Until a patch is released, restrict access to the RTMKit plugin's administrative and configuration interfaces to only trusted and necessary users, employing the principle of least privilege. 3. Conduct a thorough audit of user accounts with access to WordPress admin and RTMKit functionalities, revoking unnecessary privileges and enforcing strong authentication mechanisms such as MFA. 4. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests attempting to exploit authorization bypass patterns related to user-controlled keys. 5. Regularly review and harden WordPress and plugin configurations to minimize exposure, including disabling unused features or endpoints within RTMKit. 6. Monitor logs for unusual access patterns or attempts to manipulate keys or access restricted areas of the plugin. 7. Educate site administrators and developers about the vulnerability and encourage vigilance in plugin management and security best practices. 8. Consider isolating critical WordPress instances or using containerization to limit the blast radius in case of exploitation.
