CVE-2026-22466 identifies a missing authorization vulnerability in the WP MapIt plugin for WordPress, developed by Chandni Patel, affecting versions up to and including 3.0.3. The flaw stems from incorrectly configured access control mechanisms, allowing users with limited privileges (PR:L) to perform unauthorized actions that can alter data integrity within the plugin's functionality. The vulnerability does not require user interaction (UI:N) and can be exploited remotely (AV:N) with low attack complexity (AC:L). The scope remains unchanged (S:U), meaning the impact is confined to the vulnerable component without affecting other system components. The CVSS score of 4.3 reflects a medium severity, primarily due to the integrity impact without confidentiality or availability compromise. No known exploits have been reported in the wild, and no official patches have been linked at the time of publication. The vulnerability could be leveraged by authenticated users with limited privileges to manipulate map-related data or configurations, potentially leading to misinformation or unauthorized changes on affected WordPress sites. This issue highlights the importance of robust access control enforcement within WordPress plugins, especially those handling user-generated or location-based data.

For European organizations, the primary impact of this vulnerability lies in the potential unauthorized modification of map data or configurations on websites using the WP MapIt plugin. This could lead to misinformation being displayed to end-users, undermining trust and possibly affecting business operations relying on accurate location data. While confidentiality and availability are not directly impacted, the integrity compromise could have reputational consequences, especially for organizations in sectors like tourism, logistics, or public services that depend on accurate geospatial information. Since exploitation requires at least limited privileges, insider threats or compromised low-privilege accounts pose a risk. The absence of known exploits reduces immediate risk, but organizations should remain vigilant. The medium severity suggests that while the threat is not critical, it warrants timely attention to prevent potential misuse.

European organizations should implement the following specific mitigations: 1) Immediately audit user roles and permissions within WordPress to ensure that only trusted users have access to WP MapIt functionalities. 2) Restrict plugin access to administrators or highly trusted roles to minimize the risk of exploitation by low-privilege users. 3) Monitor logs for unusual activities related to WP MapIt, such as unexpected changes to map data or configurations. 4) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 5) Stay informed about official patches or updates from the plugin developer and apply them promptly once released. 6) Consider temporarily disabling the plugin if it is not critical to operations until a fix is available. 7) Educate site administrators about the risks of privilege escalation and the importance of strong password policies to prevent unauthorized access. These measures go beyond generic advice by focusing on access control tightening and proactive monitoring tailored to this plugin's context.
