CVE-2025-63067 identifies a missing authorization vulnerability in the Porto Theme - Functionality plugin, versions up to and including 3.6.2, developed by p-themes. This vulnerability arises from improperly configured access control mechanisms within the plugin, allowing users with low privileges (PR:L) to access functionality or data that should be restricted. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N). The impact is limited to confidentiality (C:L), with no impact on integrity or availability. The plugin is commonly used in WordPress environments to enhance theme functionality, often in e-commerce or business websites. The lack of proper authorization checks means that an authenticated but low-privileged user could potentially access sensitive information or functionality beyond their intended permissions. Although no known exploits are currently in the wild and no patches have been released, the vulnerability represents a risk that could be leveraged for information disclosure or reconnaissance. The CVSS vector indicates that the attack complexity is low (AC:L), and the scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component without impacting other components.

For European organizations, especially those operating WordPress-based websites using the Porto Theme - Functionality plugin, this vulnerability could lead to unauthorized disclosure of sensitive information, potentially including customer data or internal configuration details. While the impact is limited to confidentiality and does not affect integrity or availability, unauthorized data access can still result in reputational damage, regulatory non-compliance (e.g., GDPR), and potential exploitation in chained attacks. E-commerce sites and businesses relying on this theme for critical functionality may face increased risk if attackers leverage this vulnerability to gather intelligence or escalate privileges. The absence of known exploits reduces immediate risk, but the medium severity and ease of exploitation warrant proactive mitigation. Organizations with multi-tenant or shared hosting environments may face additional risks if attackers use this vulnerability to access data across accounts.

1. Immediately audit user roles and permissions within WordPress to ensure that only trusted users have access to the Porto Theme - Functionality plugin features. 2. Restrict access to the plugin’s administrative and functional endpoints using web application firewalls (WAFs) or access control lists (ACLs) to limit exposure to authenticated users with legitimate needs. 3. Monitor logs for unusual access patterns or privilege escalations related to the plugin’s functionality. 4. Implement network segmentation and least privilege principles to minimize the impact of compromised accounts. 5. Stay informed on vendor updates and apply patches promptly once released. 6. Consider temporarily disabling or replacing the plugin if critical until a secure version is available. 7. Conduct regular security assessments and penetration tests focusing on WordPress plugins and themes to detect similar authorization issues. 8. Educate administrators and developers on secure configuration and the risks of missing authorization checks.
