CVE-2026-2087 identifies a SQL injection vulnerability in SourceCodester Online Class Record System version 1.0, specifically within the /admin/login.php script. The vulnerability arises from improper sanitization of the user_email parameter, which is directly used in SQL queries, allowing attackers to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially extracting sensitive information, modifying data, or causing denial of service by corrupting database integrity. The vulnerability has been assigned a CVSS 4.0 score of 6.9, reflecting medium severity due to its remote exploitability and impact on confidentiality, integrity, and availability, albeit with limited scope and no authentication required. Although no public exploit code is currently confirmed in the wild, the presence of a published exploit increases the risk of future attacks. The lack of official patches or vendor advisories necessitates immediate defensive measures. This vulnerability is particularly concerning for educational institutions or organizations using this specific version of the SourceCodester Online Class Record System, as it could lead to unauthorized access to student records or administrative data. The vulnerability’s exploitation could compromise sensitive academic data, disrupt administrative operations, and potentially facilitate further attacks within the affected network environment.

The potential impact of CVE-2026-2087 is significant for organizations using the affected software. Successful exploitation can lead to unauthorized disclosure of sensitive data, including student records and administrative credentials, undermining confidentiality. Attackers could also alter or delete data, affecting data integrity and potentially disrupting educational operations. The vulnerability could be leveraged to escalate attacks within the network, potentially compromising additional systems. Since the flaw requires no authentication and can be exploited remotely, the attack surface is broad, increasing the risk of widespread exploitation. The absence of patches or mitigations from the vendor exacerbates the threat, leaving organizations exposed. Educational institutions and organizations relying on this system for critical record-keeping face operational disruptions and reputational damage if exploited. Furthermore, regulatory compliance issues may arise due to unauthorized data exposure, leading to legal and financial consequences.

To mitigate CVE-2026-2087, organizations should immediately implement strict input validation and sanitization on the user_email parameter within /admin/login.php to prevent SQL injection. Employing parameterized queries or prepared statements is essential to eliminate direct injection risks. If source code modification is not feasible, deploying a Web Application Firewall (WAF) with rules specifically targeting SQL injection patterns can provide a temporary protective layer. Monitoring and logging all login attempts and database queries for anomalous activity can help detect exploitation attempts early. Organizations should isolate the affected system within segmented network zones to limit lateral movement if compromised. Regular backups of the database should be maintained to enable recovery in case of data corruption. Additionally, organizations should engage with the vendor or community for patches or updates and consider upgrading to newer, more secure versions if available. User awareness training for administrators on recognizing suspicious activity related to this vulnerability is also recommended.
