CVE-2026-0698 identifies a SQL injection vulnerability in the Intern Membership Management System version 1.0 developed by code-projects. The vulnerability is located in the /intern/admin/edit_students.php script, specifically involving the admin_id parameter. Improper input validation or sanitization allows an attacker with administrative privileges to inject malicious SQL code remotely. The vulnerability does not require user interaction but does require the attacker to be authenticated with high privileges, likely an admin user. The CVSS 4.0 base score is 5.1 (medium), reflecting the moderate impact and exploitation complexity. The vulnerability could allow attackers to manipulate database queries, potentially leading to unauthorized data disclosure, data modification, or denial of service conditions affecting the membership management system. No official patches have been linked yet, and while the exploit details are public, there are no confirmed reports of exploitation in the wild. The vulnerability affects only version 1.0 of the product, indicating that later versions may have addressed this issue or that the product is no longer maintained.

The SQL injection vulnerability can lead to unauthorized access or manipulation of sensitive membership data stored in the backend database. This can compromise confidentiality by exposing personal or organizational data, integrity by allowing unauthorized data modification, and availability by potentially causing database errors or service disruption. Since the vulnerability requires administrative privileges, the risk is somewhat mitigated by the need for authentication; however, if admin credentials are compromised or weak, attackers can exploit this flaw to escalate their control over the system. Organizations relying on this membership management system could face data breaches, reputational damage, and operational disruptions. The impact is particularly significant for institutions managing sensitive intern or membership records, such as educational institutions, non-profits, or corporate internship programs.

1. Immediate mitigation should include restricting access to the /intern/admin/edit_students.php endpoint to trusted administrators only and enforcing strong authentication mechanisms such as multi-factor authentication to reduce the risk of credential compromise. 2. Implement input validation and parameterized queries or prepared statements in the code to prevent SQL injection attacks. 3. Monitor logs for unusual admin activity or suspicious SQL errors that could indicate attempted exploitation. 4. If possible, upgrade to a newer version of the Intern Membership Management System that addresses this vulnerability or apply vendor-provided patches once available. 5. Consider deploying web application firewalls (WAFs) with SQL injection detection rules to provide an additional layer of defense. 6. Conduct regular security assessments and code reviews of custom or legacy applications to identify and remediate injection flaws proactively. 7. Limit database user permissions associated with the application to the minimum necessary to reduce potential damage from injection attacks.
