Vulnerability Details
The vulnerability identified as CVE-2026-0733 affects the PHPGurukul Online Course Registration System up to version 3.1. The vulnerability allows for SQL injection which can be exploited remotely. The official CVE description states that this vulnerability impacts an unknown function of the file /onlinecourse/admin/manage-students.php.
The CVSS v3.1 score is 6.3, indicating a medium severity level based on confidentiality, integrity, and availability impacts being rated as low. The attack complexity is low, and it requires low privileges with no user interaction.
The vulnerability was published on January 9, 2026, and has been analyzed by the vendor. The CWE classifications associated with this vulnerability include CWE-89 (SQL Injection) and CWE-74 (Injection).
Technical Analysis
The root cause of this vulnerability stems from inadequate validation of user-supplied input. Specifically, the application allows for manipulation of the argument id/cid without proper sanitization, which leads to SQL injection vulnerabilities.
The attack vector for this vulnerability is network-based (AV:N), which means that an attacker can exploit it remotely without physical access to the vulnerable system. The attack complexity is low (AC:L), indicating that the exploit does not require advanced skills or resources.
Privileges required are low (PR:L), meaning that an attacker does not require any special permissions to exploit this vulnerability. Furthermore, user interaction is not needed (UI:N), which makes it easier for attackers to execute the exploit.
The potential impact includes low confidentiality, integrity, and availability impacts, with the exploit being categorized as proof of concept. This indicates that while it may not lead to severe damage, exploitation could compromise sensitive data and functionality.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive information through SQL injection attacks. Although the CVSS score is low, the existence of publicly disclosed exploits means that the vulnerability could be targeted by attackers.
Organizations should assess their exposure to this vulnerability based on their deployment of the PHPGurukul Online Course Registration System and the associated risk of exploitation. Given the low CVSS score, this vulnerability should be addressed but may not require immediate escalation.
Prioritizing patching in the upcoming cycles is essential to ensure that any potential attack vectors are closed off. Regular security assessments and vulnerability management processes should include checks for vulnerabilities like these.
