CVE-2025-62751 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Extend Themes Vireo product, affecting versions up to 1.0.24. This vulnerability arises from incorrectly configured access control security levels, allowing an attacker who has some level of privileges (PR:L) to perform unauthorized actions that impact the integrity of the system or data. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), but it does require the attacker to have some level of privileges, which limits exploitation to insiders or compromised accounts. The vulnerability does not affect confidentiality or availability but allows unauthorized modification or manipulation of data or settings within the Vireo theme environment. No public exploits or active exploitation in the wild have been reported to date. The lack of a patch link indicates that a fix may not yet be available, emphasizing the need for interim mitigation strategies. The vulnerability's medium severity rating (CVSS 4.3) reflects its moderate impact and exploitation complexity. Organizations using Extend Themes Vireo, particularly in web hosting or content management systems, should assess their exposure and implement strict access control policies to prevent unauthorized privilege escalation or misuse.

For European organizations, this vulnerability poses a risk primarily to the integrity of web content or configurations managed via the Vireo theme. Unauthorized modifications could lead to defacement, misinformation, or configuration changes that degrade service quality or security posture. While confidentiality and availability are not directly impacted, integrity breaches can undermine trust and compliance, especially in regulated sectors such as finance, healthcare, and government. Organizations relying on Extend Themes Vireo for their web presence or internal portals may face reputational damage and operational disruptions if attackers exploit this vulnerability. The requirement for some privilege level reduces the risk from external attackers but increases concern about insider threats or compromised accounts. Given the interconnected nature of European digital infrastructure, even moderate vulnerabilities can have cascading effects if exploited in critical sectors.

1. Conduct a thorough review of access control configurations within the Extend Themes Vireo environment to ensure that only authorized users have the necessary privileges. 2. Implement the principle of least privilege by restricting user roles and permissions to the minimum required for their functions. 3. Monitor logs and audit trails for unauthorized or suspicious modification attempts related to theme configurations. 4. If a patch becomes available, prioritize its deployment in all affected environments. 5. Use network segmentation and firewall rules to limit access to management interfaces of the Vireo theme to trusted users and systems. 6. Educate administrators and users about the risks of privilege misuse and enforce strong authentication mechanisms to reduce the risk of account compromise. 7. Consider deploying web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting the theme management functions. 8. Regularly back up theme configurations and web content to enable quick restoration in case of unauthorized changes.
