CVE-2025-64283 identifies an authorization bypass vulnerability in the Rometheme RTMKit plugin, which is used as an add-on for the popular Elementor page builder on WordPress sites. The vulnerability stems from incorrect access control configurations that allow attackers to supply user-controlled keys to circumvent authorization checks. This means that an attacker, potentially without authentication, could manipulate input parameters or keys to gain unauthorized access to restricted areas or functions within the plugin. The affected versions include all releases up to and including 1.6.7. Since RTMKit integrates with Elementor, a widely used WordPress plugin, the attack surface is significant. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. No CVSS score has been assigned yet, and no public exploits have been reported. However, the nature of the flaw suggests that an attacker could escalate privileges or access sensitive data by exploiting the misconfigured access control mechanisms. The lack of available patches at the time of publication means that affected organizations must rely on interim mitigations and heightened monitoring until a fix is released.

For European organizations, this vulnerability could lead to unauthorized access to sensitive website management functions or data, potentially resulting in data breaches, defacement, or further compromise of web infrastructure. Since many European companies rely on WordPress and Elementor for their web presence, the risk extends to a broad range of sectors including e-commerce, media, and government websites. Exploitation could undermine confidentiality by exposing private data, integrity by allowing unauthorized content changes, and availability if attackers disrupt site operations. The absence of authentication requirements lowers the barrier for attackers, increasing the likelihood of exploitation. This could also affect compliance with EU data protection regulations such as GDPR if personal data is exposed or mishandled. The reputational damage and potential financial losses from such incidents could be significant.

Organizations should immediately inventory their WordPress installations to identify the presence of RTMKit plugin versions up to 1.6.7. Until an official patch is released, administrators should restrict access to the WordPress admin interface and plugin settings to trusted IP addresses or VPNs. Implementing Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests containing manipulated keys can help mitigate exploitation attempts. Regularly monitoring logs for unusual access patterns or unauthorized privilege escalations is critical. Additionally, organizations should review and tighten access control policies within the plugin configuration and limit user permissions to the minimum necessary. Once a patch becomes available, prompt application is essential. Educating site administrators about this vulnerability and encouraging them to avoid installing untrusted plugins or updates from unofficial sources will further reduce risk.
