CVE-2025-64634 is a missing authorization vulnerability identified in the ThemeFusion Avada WordPress theme, affecting versions up to and including 7.13.1. The vulnerability arises because certain functionalities within the theme are not properly constrained by Access Control Lists (ACLs), allowing authenticated users with limited privileges (low privilege level) to access or invoke administrative or sensitive functions that should be restricted. This lack of proper authorization checks can lead to unauthorized actions that compromise the confidentiality, integrity, and availability of the affected WordPress site. The vulnerability is remotely exploitable over the network without requiring user interaction, increasing its risk profile. The CVSS 3.1 base score of 8.8 reflects a high severity with network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are currently known, the vulnerability's nature makes it a prime target for attackers seeking to escalate privileges or take over websites running Avada. The theme's widespread use in Europe for business, e-commerce, and government websites amplifies the potential impact. The lack of available patches at the time of disclosure necessitates immediate risk mitigation and monitoring by administrators.

For European organizations, the impact of CVE-2025-64634 can be severe. Avada is one of the most popular WordPress themes, widely used across Europe for corporate, governmental, and e-commerce websites. Exploitation could allow attackers with low-level authenticated access to escalate privileges, manipulate website content, steal sensitive customer or organizational data, or disrupt services. This can lead to reputational damage, regulatory penalties under GDPR for data breaches, financial losses from downtime or fraud, and potential lateral movement within organizational networks. Public sector websites could face defacement or misinformation campaigns, while e-commerce platforms risk theft of payment or personal data. The vulnerability's ease of exploitation and high impact on confidentiality, integrity, and availability make it a critical concern for European entities relying on Avada for their web presence.

1. Immediately monitor for updates from ThemeFusion and apply patches as soon as they are released. 2. Until patches are available, restrict access to WordPress administrative and theme management interfaces to trusted IP addresses using firewall rules or VPNs. 3. Implement strict role-based access controls within WordPress to limit the number of users with privileges that could exploit this vulnerability. 4. Enable and review detailed logging of administrative actions and unusual activities to detect potential exploitation attempts early. 5. Use Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting Avada theme endpoints. 6. Regularly audit installed plugins and themes to ensure they are up to date and remove unused or outdated components. 7. Educate site administrators about the risks and signs of exploitation to improve incident response readiness. 8. Consider temporary disabling or replacing the Avada theme if critical until a secure version is available.
