CVE-2025-63031 is a Missing Authorization vulnerability classified under CWE-862 found in the WP Grids EasyTest WordPress plugin, affecting versions up to 1.0.1. This vulnerability arises from incorrectly configured access control security levels, allowing unauthenticated attackers to perform actions that should require authorization. Specifically, the flaw permits remote attackers to bypass authorization checks, potentially modifying plugin data or settings without proper privileges. The vulnerability has a CVSS 3.1 base score of 5.3, reflecting a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact affects integrity (I:L) but not confidentiality or availability. No patches or fixes have been released yet, and no known exploits have been observed in the wild. The vulnerability’s presence in a WordPress plugin means it could be widely exposed on websites using this plugin, especially if administrative interfaces are accessible externally. The lack of authentication requirement increases the risk of exploitation, although the impact is limited to integrity rather than data disclosure or service disruption. This vulnerability highlights the importance of proper access control implementation in WordPress plugins to prevent unauthorized actions.

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of web content or plugin configurations managed via WP Grids EasyTest. Unauthorized modification could lead to defacement, misinformation, or unauthorized changes in website behavior, potentially damaging brand reputation and user trust. Since the vulnerability does not affect confidentiality or availability, direct data breaches or denial of service are less likely. However, integrity compromises can still facilitate further attacks, such as injecting malicious content or redirecting users to phishing sites. Organizations relying heavily on WordPress for customer-facing websites, e-commerce platforms, or internal portals could experience operational disruptions or compliance issues if unauthorized changes go undetected. The absence of required authentication and user interaction lowers the barrier for exploitation, increasing the risk of automated attacks. European entities with stringent data integrity and compliance requirements (e.g., GDPR) must consider the potential legal and regulatory implications of unauthorized data modifications.

1. Monitor WP Grids vendor communications closely for official patches or updates addressing CVE-2025-63031 and apply them promptly upon release. 2. Restrict access to WordPress administrative and plugin management interfaces using IP whitelisting, VPNs, or multi-factor authentication to reduce exposure. 3. Conduct regular audits of user roles and permissions within WordPress to ensure only authorized personnel have plugin management capabilities. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the EasyTest plugin endpoints. 5. Disable or remove the EasyTest plugin if it is not essential to reduce the attack surface. 6. Employ monitoring and alerting on changes to plugin configurations or website content to detect unauthorized modifications quickly. 7. Educate web administrators about the risks of missing authorization vulnerabilities and the importance of secure plugin management practices. 8. Consider isolating critical WordPress instances or using containerization to limit the impact of potential compromises.
