CVE-2025-49925 identifies a missing authorization vulnerability in the VibeThemes WPLMS WordPress plugin, specifically affecting versions up to 1.9.9.7. The flaw arises because certain functionality within the plugin is not properly constrained by Access Control Lists (ACLs), allowing unauthenticated remote attackers to invoke functions that should require authorization. This lack of proper access control means attackers can potentially access or manipulate data and system functions that should be restricted, leading to information disclosure, data integrity compromise, or disruption of service. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, increasing its risk profile. Although no public exploits have been reported yet, the CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) indicates a high-severity issue with low attack complexity and significant impact on confidentiality, integrity, and availability. WPLMS is a popular WordPress-based learning management system used by educational institutions and enterprises to deliver online courses, making this vulnerability particularly concerning for organizations relying on it for critical training and educational services. The vulnerability was reserved in June 2025 and published in October 2025, with no patch links currently available, emphasizing the need for immediate attention and mitigation by administrators.

For European organizations, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their e-learning platforms. Unauthorized access could lead to exposure of sensitive educational content, user data including personal information, and administrative controls. Attackers might alter course materials, disrupt learning activities, or escalate attacks to broader network resources if the compromised system is connected internally. Educational institutions, corporate training departments, and government agencies using WPLMS could face operational disruptions, reputational damage, and regulatory compliance issues under GDPR due to data breaches. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially on public-facing LMS deployments. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score suggests that exploitation could have serious consequences if weaponized.

Since no official patches are currently available, European organizations should immediately implement compensating controls. These include restricting network access to the WPLMS plugin endpoints via web application firewalls (WAFs) or IP whitelisting to limit exposure. Administrators should audit and tighten WordPress user roles and permissions to minimize potential damage. Monitoring and logging access to the LMS for unusual or unauthorized activity is critical to detect exploitation attempts early. Organizations should subscribe to vendor and security advisories for timely patch releases and apply updates promptly once available. Additionally, consider isolating the LMS environment from critical internal networks to contain potential breaches. Conducting penetration testing focused on authorization controls can help identify other weaknesses. Finally, educating staff about the vulnerability and encouraging vigilance against suspicious activity will enhance overall security posture.
