CVE-2026-0728 is an SQL injection vulnerability identified in version 1.0 of the code-projects Intern Membership Management System. The vulnerability arises from improper sanitization of the admin_id parameter processed by the /intern/admin/delete_admin.php script. An attacker with authenticated access can remotely manipulate this parameter to inject malicious SQL queries into the backend database. This can result in unauthorized reading, modification, or deletion of data stored within the system. The vulnerability is classified as medium severity with a CVSS 4.0 base score of 5.1, reflecting that exploitation requires high privileges (authenticated admin access) but no user interaction. The impact on confidentiality, integrity, and availability is limited but non-negligible due to the potential for data compromise or administrative disruption. No patches or fixes have been linked yet, and no known exploits are reported in the wild, but public disclosure increases the risk of future exploitation. The vulnerability affects only version 1.0 of the product, so organizations running this specific version are at risk. The attack vector is network-based, allowing remote exploitation over the internet or internal networks if access controls are insufficient. The lack of user interaction needed simplifies exploitation for authenticated attackers. Given the administrative nature of the affected functionality, the vulnerability could be leveraged to escalate privileges or disrupt membership management operations.

For European organizations, this vulnerability poses a risk primarily to those using the affected Intern Membership Management System version 1.0, particularly in sectors managing sensitive intern or membership data such as universities, professional associations, or corporate internship programs. Exploitation could lead to unauthorized disclosure or alteration of membership records, potentially violating data protection regulations like GDPR. The integrity of administrative data could be compromised, leading to operational disruptions or reputational damage. Although exploitation requires authenticated access, insider threats or compromised credentials could facilitate attacks. The medium severity rating indicates moderate impact, but the potential for data breaches and administrative control loss is significant. Organizations relying on this system should consider the risk of lateral movement within their networks if attackers gain a foothold. The lack of known exploits currently reduces immediate risk but does not eliminate it, especially given the public disclosure.

1. Immediately restrict access to the /intern/admin/delete_admin.php endpoint to trusted administrators only, using network segmentation and strong authentication mechanisms. 2. Implement strict input validation and parameterized queries or prepared statements in the affected code to prevent SQL injection. 3. Monitor logs for suspicious activity related to admin_id parameter usage and failed authentication attempts. 4. Apply any vendor patches or updates as soon as they become available; if no official patch exists, consider temporary workarounds such as disabling the vulnerable functionality. 5. Conduct a thorough audit of user privileges to ensure only necessary personnel have administrative access. 6. Employ Web Application Firewalls (WAFs) with SQL injection detection rules tailored to the application’s traffic patterns. 7. Educate administrators about the risks of credential compromise and enforce multi-factor authentication (MFA) for admin accounts. 8. Regularly back up membership data and test restoration procedures to minimize impact in case of data corruption or loss.
