CVE-2025-11255 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Password Policy Manager | Password Manager plugin for WordPress, developed by cyberlord92. The vulnerability exists due to the absence of proper capability checks on the 'moppm_ajax' AJAX endpoint, which is used for asynchronous server requests. This flaw allows any authenticated user with Subscriber-level privileges or higher to invoke this endpoint and perform unauthorized actions, specifically logging out the site's connection to the miniorange service. Since Subscriber-level access is typically granted to low-privilege users, this vulnerability significantly lowers the barrier for exploitation. The vulnerability affects all versions up to and including 2.0.5 of the plugin. The CVSS v3.1 score is 4.3 (medium severity), reflecting that the attack vector is network-based, requires low privileges, no user interaction, and impacts integrity but not confidentiality or availability. Although no public exploits have been reported yet, the vulnerability could be leveraged to disrupt authentication integrations relying on miniorange, potentially causing operational disruptions or forcing re-authentication flows. The vulnerability does not directly expose sensitive data but undermines trust in session management and plugin integrity. The lack of a patch link suggests that users should monitor vendor updates closely. The vulnerability is particularly relevant for WordPress sites that integrate with miniorange services for authentication or password policy enforcement.

For European organizations, the vulnerability poses a risk primarily to the integrity of authentication-related processes on WordPress sites using the affected plugin. Attackers with low-level authenticated access can disrupt the connection to miniorange, potentially causing users to be logged out unexpectedly or forcing re-authentication. This can lead to operational disruptions, user frustration, and increased support costs. While confidentiality and availability are not directly impacted, the integrity compromise could be a vector for further attacks if combined with other vulnerabilities or social engineering. Organizations relying heavily on WordPress for customer-facing or internal portals, especially those using miniorange for single sign-on or multi-factor authentication, may experience degraded security posture and trust issues. The vulnerability could also be exploited to create denial-of-service-like conditions by repeatedly logging out users, impacting service continuity. Given the widespread use of WordPress in Europe, especially in sectors like government, education, and SMEs, the impact could be significant if not addressed promptly.

1. Monitor the vendor’s official channels for patches or updates addressing CVE-2025-11255 and apply them immediately upon release. 2. Until a patch is available, restrict Subscriber-level and other low-privilege user access to the WordPress admin dashboard and sensitive AJAX endpoints by implementing stricter role-based access controls. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized AJAX requests targeting the 'moppm_ajax' endpoint from low-privilege users. 4. Audit and monitor logs for unusual logout patterns or repeated AJAX calls to the vulnerable endpoint to detect potential exploitation attempts early. 5. Consider temporarily disabling the Password Policy Manager plugin if the risk outweighs the benefits and no patch is available. 6. Educate site administrators about the risks of granting Subscriber-level access broadly and encourage the principle of least privilege. 7. Harden WordPress installations by disabling unused plugins and endpoints and keeping all components up to date to reduce attack surface.
