CVE-2025-15347 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Creator LMS plugin for WordPress, used widely by creators, coaches, and trainers to manage learning content. The flaw resides in the get_items_permissions_check function, which lacks proper capability checks, allowing authenticated users with contributor-level privileges or higher to update arbitrary WordPress options without proper authorization. This missing authorization enables privilege escalation, as attackers can modify critical settings that may lead to full administrative control over the WordPress site. The vulnerability affects all versions up to and including 1.1.12 of the plugin. The CVSS 3.1 base score is 8.8, reflecting its network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and high impact on confidentiality, integrity, and availability. Although no public exploits have been reported, the vulnerability’s nature makes it a prime target for attackers seeking to compromise WordPress-based LMS platforms. The absence of a patch at the time of publication increases the urgency for organizations to implement interim mitigations. This vulnerability could be exploited remotely over the network by any authenticated contributor, making it a significant risk for multi-user WordPress environments.

For European organizations, the impact of CVE-2025-15347 can be severe, especially for those using Creator LMS to deliver training and educational content. Unauthorized modification of WordPress options can lead to site defacement, data leakage, installation of backdoors, or complete takeover of the WordPress environment. This compromises the confidentiality of sensitive training materials and user data, the integrity of the learning platform, and the availability of services. Organizations in sectors such as education, corporate training, and coaching services may face operational disruptions and reputational damage. Additionally, attackers could leverage this vulnerability to pivot into broader network environments if the WordPress instance is integrated with other internal systems. Given the widespread use of WordPress in Europe and the growing reliance on LMS platforms, the threat poses a significant risk to business continuity and data protection compliance under regulations like GDPR.

1. Monitor the Creator LMS plugin vendor’s channels for an official patch and apply it immediately upon release. 2. Until a patch is available, restrict contributor-level access to trusted users only and review user roles to minimize unnecessary privileges. 3. Implement WordPress security plugins that can monitor and alert on changes to critical options and configurations. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the get_items_permissions_check function or option modification endpoints. 5. Conduct regular audits of WordPress option settings and user activity logs to detect unauthorized changes early. 6. Consider isolating the LMS environment from other critical infrastructure to limit lateral movement in case of compromise. 7. Educate administrators and content creators about the risks of privilege escalation and enforce strong authentication mechanisms.
