CVE-2025-6184 is a critical SQL Injection vulnerability identified in the Tutor LMS Pro plugin for WordPress, affecting all versions up to and including 3.7.0. The vulnerability stems from insufficient escaping and lack of proper parameterization of the 'order' parameter within the get_submitted_assignments() function. This parameter is user-supplied and used directly in SQL queries without adequate sanitization, enabling attackers with authenticated Tutor-level access or higher to append arbitrary SQL commands. The attack vector is time-based SQL Injection, which allows attackers to infer data by measuring response delays, facilitating extraction of sensitive information such as user data, course content, or administrative credentials from the underlying database. The vulnerability impacts confidentiality, integrity, and availability, as attackers can manipulate database queries, potentially altering or deleting data and disrupting service. The CVSS 3.1 base score is 8.8, reflecting network attack vector, low attack complexity, required privileges (low-level authenticated user), no user interaction, and high impact on confidentiality, integrity, and availability. No public exploits have been reported yet, but the vulnerability is publicly disclosed and should be considered exploitable. The issue affects only the Pro version of Tutor LMS, a popular eLearning plugin used by educational institutions and online course providers on WordPress platforms worldwide.

The impact of CVE-2025-6184 is significant for organizations using Tutor LMS Pro, especially educational institutions, training providers, and enterprises relying on WordPress-based eLearning solutions. Successful exploitation can lead to unauthorized disclosure of sensitive data including student records, course materials, and potentially administrative credentials. Attackers could also modify or delete data, disrupting learning operations and damaging organizational reputation. The requirement for authenticated access at Tutor-level privileges limits exposure to some extent but does not eliminate risk, as such accounts are commonly held by instructors or course managers who may be targeted via social engineering or credential compromise. The vulnerability could facilitate lateral movement within the network if attackers escalate privileges after database access. Given the widespread use of WordPress and the growing adoption of eLearning platforms, the scope of affected systems is broad, potentially impacting organizations globally. The high CVSS score underscores the critical nature of this vulnerability and the urgency for remediation to prevent data breaches and operational disruptions.

To mitigate CVE-2025-6184, organizations should immediately upgrade Tutor LMS Pro to a patched version once available from the vendor. In the absence of an official patch, administrators should implement the following specific measures: 1) Restrict Tutor-level user privileges to the minimum necessary and audit existing accounts for suspicious activity. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block anomalous SQL query patterns, particularly targeting the 'order' parameter in requests to the get_submitted_assignments() function. 3) Conduct code reviews and apply manual input validation or parameterized queries to sanitize the 'order' parameter if custom modifications are possible. 4) Monitor database logs and application logs for unusual query patterns or delays indicative of time-based SQL Injection attempts. 5) Enforce strong authentication mechanisms and consider multi-factor authentication for all users with elevated privileges to reduce risk of credential compromise. 6) Regularly back up databases and test restoration procedures to minimize impact of potential data tampering or deletion. 7) Educate staff on phishing and social engineering risks to prevent account takeover. These targeted mitigations complement general security hygiene and reduce the attack surface until a vendor patch is deployed.
