CVE-2025-15347 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Creator LMS plugin for WordPress, a learning management system designed for creators, coaches, and trainers. The issue arises from the get_items_permissions_check function, which lacks proper capability checks, allowing authenticated users with contributor-level privileges or higher to modify arbitrary WordPress options without proper authorization. This missing authorization check means that an attacker who has limited access to the WordPress backend can escalate their privileges by altering critical site settings, potentially leading to full site takeover. The vulnerability affects all versions of the plugin up to and including 1.1.12. The CVSS v3.1 score of 8.8 reflects a high severity, with an attack vector that is network-based, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability at a high level. While no public exploits have been reported yet, the vulnerability's nature makes it a prime candidate for exploitation once weaponized. The lack of a patch link suggests that users must monitor vendor updates closely or implement temporary mitigations. This vulnerability is particularly dangerous because WordPress options control fundamental site behavior, and unauthorized changes can lead to persistent backdoors, data leakage, or site defacement.

The impact of CVE-2025-15347 is significant for organizations using the Creator LMS plugin on WordPress sites. An attacker with contributor-level access can escalate privileges to administrator level by modifying critical WordPress options, potentially leading to full site compromise. This can result in unauthorized data disclosure, data manipulation, installation of malicious code, or complete denial of service. Educational institutions, coaching platforms, and training providers relying on Creator LMS are at risk of losing sensitive user data and damaging their reputation. The vulnerability undermines the integrity and availability of the LMS platform, disrupting learning activities and potentially causing financial and operational losses. Since WordPress powers a large portion of the web, and LMS plugins are widely used in e-learning, the scope of affected systems is broad, increasing the potential for widespread exploitation.

To mitigate CVE-2025-15347, organizations should immediately restrict contributor-level user privileges to trusted individuals only and audit existing user roles for unnecessary permissions. Until an official patch is released, consider disabling or removing the Creator LMS plugin if feasible. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the get_items_permissions_check function or attempts to modify WordPress options by unauthorized users. Regularly monitor WordPress logs for unusual activity related to option updates. Employ the principle of least privilege by limiting plugin access and using multi-factor authentication for all backend users. Stay updated with vendor announcements for patches and apply them promptly once available. Additionally, conduct security assessments of WordPress plugins to identify similar authorization issues proactively.
