CVE-2025-49925 identifies a missing authorization vulnerability in the VibeThemes WPLMS WordPress plugin, specifically versions up to 1.9.9.7. The vulnerability arises because certain functionality within the plugin is not properly constrained by Access Control Lists (ACLs), allowing unauthorized users to invoke functions or access features that should be restricted. This type of flaw typically results from inadequate checks on user permissions before executing sensitive operations. WPLMS is a popular learning management system plugin used to deliver and manage online courses within WordPress environments. The missing authorization can enable attackers to perform unauthorized actions such as viewing or modifying course content, user data, or administrative settings, potentially compromising the confidentiality and integrity of the LMS data. No CVSS score has been assigned yet, and no known exploits are currently reported in the wild, indicating that the vulnerability might be newly disclosed or not yet weaponized. The vulnerability was reserved in June 2025 and published in October 2025. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for vigilance and interim protective measures. Since WPLMS is a plugin running within WordPress, exploitation requires the attacker to have network access to the WordPress site hosting the plugin. The flaw does not require user interaction, making it easier to exploit if the attacker can reach the vulnerable endpoint. Overall, this vulnerability represents a significant risk to organizations relying on WPLMS for their e-learning platforms, as unauthorized access could lead to data breaches, unauthorized content changes, or disruption of educational services.

For European organizations using WPLMS, this vulnerability could lead to unauthorized access to sensitive educational content, user personal data, and administrative controls within the LMS. Confidentiality is at risk because attackers could view restricted information. Integrity could be compromised if unauthorized users modify course materials or user records. Availability impact is less direct but could occur if attackers disrupt LMS operations through unauthorized actions. Educational institutions, corporate training departments, and e-learning service providers in Europe relying on WPLMS may suffer reputational damage, regulatory penalties under GDPR if personal data is exposed, and operational disruptions. The lack of authentication barriers for exploitation increases the risk, especially for publicly accessible LMS portals. Since no public exploits are known yet, the window for proactive mitigation is open, but the risk remains significant due to the critical nature of LMS data and services.

1. Monitor VibeThemes and official WPLMS channels closely for security patches addressing CVE-2025-49925 and apply them immediately upon release. 2. Conduct a thorough audit of ACL and permission configurations within the WPLMS plugin to ensure that all sensitive functions are properly restricted. 3. Restrict network access to the WordPress sites hosting WPLMS to trusted IP ranges where possible, using firewalls or VPNs to reduce exposure. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting WPLMS endpoints. 5. Regularly review LMS user activity logs for unusual access patterns or unauthorized actions. 6. Consider temporarily disabling or limiting access to vulnerable WPLMS features until a patch is available. 7. Educate LMS administrators on the importance of least privilege principles and secure plugin management. 8. Maintain regular backups of LMS data to enable recovery in case of compromise. These steps go beyond generic advice by focusing on access control audits, network-level restrictions, and proactive monitoring tailored to the WPLMS environment.
