CVE-2025-62751 is a vulnerability identified in the Extend Themes Vireo product, affecting versions up to 1.0.24. The root cause is a missing authorization check (CWE-862), which means that the software fails to properly verify whether a user has the necessary permissions before allowing certain actions. This can lead to privilege escalation or unauthorized modification of data, impacting the integrity of the system. The CVSS 3.1 vector indicates the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L) and requires privileges (PR:L), but no user interaction (UI:N). The scope is unchanged (S:U), and the impact affects integrity only (I:L), with no confidentiality or availability impact. No patches or exploits are currently available, but the vulnerability is published and should be addressed proactively. The missing authorization typically arises from incorrectly configured access control mechanisms within the theme’s code, which may allow authenticated users with limited roles to perform unauthorized actions such as modifying theme settings or content. This vulnerability is particularly relevant for websites using the Vireo theme, often deployed on WordPress platforms, which are common in many European organizations for content management and e-commerce.

For European organizations, the impact of CVE-2025-62751 primarily concerns the integrity of web content and configurations managed through the Vireo theme. Unauthorized modifications could lead to defacement, misinformation, or disruption of business processes relying on accurate web content. While confidentiality and availability are not directly affected, integrity breaches can undermine trust and lead to reputational damage, especially for sectors like finance, government, and e-commerce. Organizations with multi-user environments where users have varying privilege levels are at higher risk, as attackers could exploit this flaw to escalate privileges or alter critical settings. The absence of known exploits reduces immediate risk, but the vulnerability’s presence in widely used themes means it could become a target once publicized. Additionally, compliance with European data protection regulations (e.g., GDPR) could be impacted if unauthorized changes lead to data integrity issues or indirect data exposure.

To mitigate CVE-2025-62751, organizations should: 1) Audit and review the access control configurations within the Vireo theme and any customizations to ensure proper authorization checks are enforced for all sensitive actions. 2) Limit user privileges strictly according to the principle of least privilege, ensuring that only trusted users have elevated roles capable of making configuration changes. 3) Monitor logs and user activities for unusual or unauthorized changes to theme settings or content. 4) Apply any vendor patches or updates promptly once available; in the absence of patches, consider temporarily disabling or replacing the vulnerable theme. 5) Employ web application firewalls (WAFs) with rules to detect and block suspicious requests targeting theme management endpoints. 6) Educate administrators and content managers about the risks of privilege misuse and encourage strong authentication practices. 7) Conduct regular security assessments and penetration tests focusing on authorization mechanisms within web applications and themes.
