CVE-2025-31525 identifies a missing authorization vulnerability in the WP Messiah WP Mobile Bottom Menu plugin for WordPress, affecting all versions up to and including 1.4.0. The vulnerability arises from incorrectly configured access control security levels, which means that certain actions or data that should be restricted to authorized users can be accessed or manipulated by unauthorized parties. This type of vulnerability typically allows attackers to perform unauthorized operations such as modifying menu configurations, injecting malicious content, or accessing sensitive plugin-related data. The plugin is intended to improve mobile navigation menus on WordPress sites, so exploitation could impact the user interface and potentially the integrity of the website’s navigation experience. No CVSS score has been assigned yet, and no public exploits have been reported, but the flaw’s nature suggests that exploitation could be straightforward if the vulnerable endpoints are accessible. The vulnerability does not require user interaction, increasing the risk of automated attacks or scanning. Since no patch or mitigation has been officially released, organizations must take interim protective measures. The vulnerability was published on April 1, 2025, with the vendor project identified as WP Messiah and the vulnerability tracked by Patchstack. The lack of a CVSS score and patch highlights the need for immediate attention from site administrators using this plugin.

The potential impact of CVE-2025-31525 is significant for organizations using the WP Messiah WP Mobile Bottom Menu plugin. Unauthorized access due to missing authorization can lead to unauthorized modification of website navigation menus, which can degrade user experience or be leveraged to insert malicious links or content, potentially facilitating phishing or malware distribution. Integrity of the website’s mobile navigation could be compromised, undermining trust and brand reputation. If attackers gain the ability to alter menu items or configurations, they might redirect users to malicious sites or disrupt legitimate site functionality, affecting availability indirectly. For e-commerce or content-heavy sites, this can result in lost revenue and customer trust. The vulnerability could also serve as a foothold for further attacks against the WordPress site, including privilege escalation or data exfiltration if combined with other vulnerabilities. Since WordPress powers a large portion of the web globally, the scope of affected systems is broad. The absence of a patch increases the window of exposure, making timely mitigation critical.

Organizations should immediately audit their WordPress installations to identify if the WP Messiah WP Mobile Bottom Menu plugin is in use and determine the version. If the plugin is present and running version 1.4.0 or earlier, consider disabling or uninstalling the plugin until an official patch is released. Restrict access to WordPress administrative interfaces and plugin endpoints using web application firewalls (WAFs) or IP whitelisting to reduce exposure. Monitor web server logs for unusual access patterns targeting the plugin’s endpoints. Implement strict role-based access controls within WordPress to limit which users can modify menu configurations. Regularly back up website data and configurations to enable quick restoration if exploitation occurs. Stay informed through vendor announcements and security advisories for the release of patches or updates. If possible, conduct penetration testing focusing on plugin access controls to identify any exploitation attempts. Consider deploying runtime application self-protection (RASP) tools that can detect and block unauthorized access attempts in real time.
