CVE-2025-64283 is a medium-severity authorization bypass vulnerability identified in the RTMKit plugin developed by Rometheme for the Elementor page builder on WordPress. The vulnerability stems from incorrectly configured access control mechanisms that rely on a user-controlled key, which attackers can manipulate to bypass authorization checks. Specifically, an attacker with low privileges (PR:L) can send crafted requests over the network (AV:N) without requiring user interaction (UI:N) to gain unauthorized access to sensitive data, impacting confidentiality (C:H) but not affecting integrity or availability. The vulnerability affects RTMKit versions up to and including 1.6.7. Although no public exploits are known at this time, the flaw presents a significant risk because it allows privilege escalation and unauthorized data access within affected WordPress environments. The root cause is the failure to properly validate or restrict the user-controlled key used in access control decisions, enabling attackers to circumvent intended security boundaries. This vulnerability is particularly concerning for organizations that rely on RTMKit for managing content or sensitive information within their Elementor-powered websites, as it could lead to data leakage or unauthorized information disclosure. The absence of published patches necessitates immediate attention to configuration and monitoring until a vendor fix is available.

For European organizations, the primary impact of CVE-2025-64283 is unauthorized disclosure of sensitive information due to the bypass of access controls in RTMKit. This can lead to exposure of confidential business data, customer information, or internal content managed via the affected plugin. Since the vulnerability does not affect data integrity or availability, the risk centers on confidentiality breaches, which can result in reputational damage, regulatory non-compliance (e.g., GDPR violations), and potential financial penalties. Organizations using RTMKit in public-facing or internal WordPress sites are at risk, especially if the plugin manages sensitive or proprietary content. The ease of exploitation (network accessible, low privileges required, no user interaction) increases the likelihood of targeted attacks or opportunistic scanning by attackers. Given the widespread use of WordPress and Elementor in Europe, this vulnerability could affect a broad range of sectors including e-commerce, media, education, and government websites. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, emphasizing the need for proactive mitigation.

1. Immediately audit RTMKit plugin configurations to ensure access control mechanisms are properly enforced and that user-controlled keys are validated or restricted. 2. Limit the privileges of users who can interact with RTMKit to the minimum necessary, reducing the attack surface. 3. Monitor web server and application logs for unusual access patterns or privilege escalation attempts related to RTMKit endpoints. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting RTMKit functionalities, especially those manipulating keys or authorization parameters. 5. Stay in close contact with Rometheme for official patches or updates addressing this vulnerability and plan prompt deployment once available. 6. Consider temporarily disabling or restricting RTMKit usage in sensitive environments until a patch is applied. 7. Conduct internal security awareness to inform administrators and developers about the risk and encourage vigilance in plugin management. 8. Regularly update WordPress core and all plugins to minimize exposure to known vulnerabilities.
