CVE-2025-58993 is a high-severity SQL Injection vulnerability (CWE-89) affecting Themeum's Tutor LMS product, specifically versions up to 3.7.4. SQL Injection occurs when an application improperly neutralizes special elements in SQL commands, allowing an attacker to manipulate backend database queries. In this case, the vulnerability enables an attacker with high privileges (PR:H) and no user interaction (UI:N) to execute crafted SQL commands remotely over the network (AV:N). The CVSS vector indicates that while the attack complexity is low (AC:L), the attacker must have some level of authenticated access to the system. The vulnerability impacts confidentiality significantly (C:H), with no direct impact on integrity (I:N) and a low impact on availability (A:L). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component, potentially impacting the entire LMS database or connected systems. Tutor LMS is a widely used learning management system plugin for WordPress, commonly deployed by educational institutions and corporate training environments. Exploitation could allow attackers to extract sensitive data such as user credentials, course content, or personal information stored in the LMS database. Although no known exploits are currently in the wild, the presence of this vulnerability in a critical educational platform poses a substantial risk if left unpatched. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls and monitor for suspicious activity. The vulnerability was reserved and published in early September 2025, indicating it is a recent discovery requiring immediate attention from administrators of affected systems.

For European organizations, especially educational institutions, universities, and corporate training providers using Tutor LMS, this vulnerability could lead to unauthorized disclosure of sensitive student and employee data, violating GDPR and other data protection regulations. The high confidentiality impact means personal identifiable information (PII), academic records, and proprietary training materials could be exposed, resulting in reputational damage and potential legal penalties. The changed scope suggests that exploitation might affect interconnected systems or databases, amplifying the damage. Additionally, the low availability impact could still disrupt LMS services, affecting learning continuity. Given the requirement for authenticated access, insider threats or compromised credentials could facilitate exploitation, emphasizing the need for strong access controls. The absence of known exploits currently provides a window for proactive defense, but the widespread use of Tutor LMS in Europe makes this a significant risk vector for cybercriminals targeting educational infrastructure.

1. Immediately audit all Tutor LMS installations to identify affected versions (up to 3.7.4) and prioritize their upgrade once patches become available. 2. Until patches are released, restrict LMS administrative access to trusted IP ranges and enforce multi-factor authentication (MFA) to reduce the risk of credential compromise. 3. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL Injection payloads targeting Tutor LMS endpoints. 4. Conduct regular database activity monitoring and anomaly detection to identify unusual query patterns indicative of exploitation attempts. 5. Review and minimize database user privileges used by Tutor LMS to the least necessary permissions, limiting potential damage from SQL Injection. 6. Educate LMS administrators about the vulnerability and encourage immediate reporting of suspicious activity. 7. Maintain up-to-date backups of LMS data to enable rapid recovery in case of data compromise or service disruption. 8. Monitor threat intelligence sources for any emerging exploits or patches related to CVE-2025-58993 and apply updates promptly.
