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 issue stems from the absence of proper capability checks on the 'moppm_ajax' AJAX endpoint, which is accessible to any authenticated user with at least Subscriber-level privileges. This lack of authorization verification allows such users to invoke actions that should be restricted, specifically the ability to log out the site's connection to the miniorange service. Miniorange is commonly used for identity and access management, including single sign-on and multi-factor authentication, so disrupting this connection could weaken the site's security posture. The vulnerability affects all plugin versions up to and including 2.0.5, with no patch currently listed. The CVSS 3.1 vector indicates the attack can be performed remotely (AV:N) with low attack complexity (AC:L), requires privileges (PR:L), no user interaction (UI:N), and impacts integrity (I:L) but not confidentiality or availability. This means an attacker with a low-level authenticated account can cause unauthorized changes without needing victim interaction. While no exploits are known in the wild, the vulnerability could be exploited to interfere with authentication mechanisms, potentially leading to broader security issues if combined with other vulnerabilities or misconfigurations. The flaw highlights the importance of enforcing strict authorization checks on all administrative or sensitive AJAX endpoints within WordPress plugins.

For European organizations, this vulnerability poses a risk primarily to the integrity of authentication and password policy enforcement mechanisms on WordPress sites using the affected plugin. Disrupting the miniorange connection could disable or degrade identity management services, potentially allowing attackers to bypass or weaken authentication controls indirectly. This could lead to unauthorized access if attackers combine this with other vulnerabilities or social engineering attacks. While the vulnerability does not directly expose confidential data or cause denial of service, the loss of control over authentication services can have cascading effects on compliance with GDPR and other data protection regulations, especially if it results in unauthorized access or data breaches. Organizations relying on WordPress for critical web services or customer portals are at higher risk. The medium severity score reflects a moderate threat level, but the ease of exploitation by low-privilege users increases the urgency for mitigation. The absence of known exploits suggests a window of opportunity for defenders to act before active attacks emerge.

1. Immediately restrict access to the 'moppm_ajax' AJAX endpoint by implementing server-side capability checks to ensure only authorized administrative users can invoke sensitive actions. 2. Monitor WordPress user roles and permissions to limit Subscriber-level accounts and audit any unexpected privilege escalations. 3. Disable or uninstall the Password Policy Manager | Password Manager plugin if it is not essential, or replace it with a more secure alternative. 4. Keep WordPress core and all plugins updated; watch for official patches from cyberlord92 addressing this vulnerability and apply them promptly. 5. Implement Web Application Firewall (WAF) rules to detect and block suspicious AJAX requests targeting the vulnerable endpoint. 6. Audit logs for unusual logout events related to miniorange connections to detect potential exploitation attempts. 7. Educate site administrators about the risks of low-privilege account misuse and enforce strong password policies and multi-factor authentication for all users. 8. Consider isolating critical authentication services from publicly accessible endpoints to reduce attack surface.
