CVE-2025-62028 is a missing authorization vulnerability identified in the ThemeNectar Salient WordPress theme, affecting all versions prior to 17.4.0. This vulnerability arises because certain theme functionalities lack proper authorization checks, allowing unauthenticated remote attackers to access restricted features or data. The CVSS 3.1 base score is 4.3, reflecting a medium severity primarily due to limited confidentiality impact without affecting integrity or availability. The attack vector is network-based (AV:A), requiring no privileges (PR:N) and no user interaction (UI:N). The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component. Although no known exploits are currently reported in the wild, the absence of authorization controls can lead to unauthorized data disclosure or information leakage, potentially exposing sensitive site information or configuration details. The vulnerability is particularly relevant for organizations using the Salient theme for their WordPress sites, which are common in business, media, and e-commerce sectors. Patch or update information is not yet provided, so organizations must monitor vendor advisories closely. Additional mitigations include restricting access to theme management interfaces and monitoring for unusual access patterns. This vulnerability highlights the importance of authorization checks in web application components to prevent unauthorized access.

For European organizations, the primary impact of CVE-2025-62028 is unauthorized access to certain theme functionalities or data on WordPress sites using the Salient theme. While the vulnerability does not allow modification or disruption of services, unauthorized data exposure can lead to information leakage, which may facilitate further attacks such as social engineering or targeted exploitation. Organizations in sectors relying heavily on WordPress for public websites, including e-commerce, media, and professional services, could face reputational damage and potential compliance issues under GDPR if personal or sensitive data is exposed. The limited scope and medium severity reduce the likelihood of widespread disruption, but the ease of exploitation without authentication increases risk for sites that have not applied patches or mitigations. Attackers could leverage this vulnerability to gather intelligence or access configuration details that aid in subsequent attacks. Therefore, the vulnerability represents a moderate threat to confidentiality and overall security posture of affected European entities.

1. Immediately monitor ThemeNectar and official Salient theme channels for the release of version 17.4.0 or later that addresses this vulnerability and apply the update as soon as it becomes available. 2. Until a patch is available, restrict access to WordPress theme management interfaces via IP whitelisting, VPNs, or web application firewalls (WAFs) to limit exposure. 3. Implement strict role-based access controls within WordPress to minimize the number of users who can modify theme settings or access sensitive theme features. 4. Enable detailed logging and monitoring of access to theme-related endpoints to detect unusual or unauthorized access attempts promptly. 5. Conduct regular security audits of WordPress installations and plugins/themes to identify and remediate missing authorization or other vulnerabilities proactively. 6. Educate site administrators about the risks of missing authorization vulnerabilities and the importance of timely updates and access control. 7. Consider deploying runtime application self-protection (RASP) or WAF rules specifically tailored to detect and block attempts to exploit missing authorization in the Salient theme.
