CVE-2026-0697 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0. The flaw exists in an unspecified function within the /intern/admin/edit_admin.php file, where the admin_id parameter is improperly sanitized. This allows an attacker to inject malicious SQL code remotely, manipulating backend database queries. The vulnerability does not require user interaction but does require the attacker to have high privileges, indicating that some form of authentication or elevated access is necessary before exploitation. The CVSS 4.0 base score is 5.1, reflecting a medium severity level due to limited confidentiality, integrity, and availability impacts (all rated low), no scope change, and no user interaction. The attack vector is network-based with low attack complexity. Although no known exploits are currently active in the wild, the existence of a published exploit increases the risk of future attacks. The vulnerability could allow unauthorized data access or modification within the membership management system, potentially compromising administrative functions and sensitive membership data. The lack of available patches necessitates interim mitigations such as input validation and restricting access to the affected functionality. This vulnerability highlights the importance of secure coding practices, especially in administrative modules that handle critical parameters like admin_id.

For European organizations utilizing the code-projects Intern Membership Management System 1.0, this vulnerability could lead to unauthorized access or modification of administrative data, undermining the confidentiality and integrity of membership information. Although exploitation requires high privileges, if an attacker gains such access, they could manipulate SQL queries to extract sensitive data, alter records, or disrupt system availability. This could result in data breaches, loss of trust, regulatory non-compliance (e.g., GDPR violations), and operational disruptions. The impact is particularly significant for organizations managing sensitive or personal data of members, such as professional associations, educational institutions, or NGOs. The medium severity rating suggests a moderate risk, but the presence of a published exploit increases urgency. European entities with limited security monitoring or delayed patch management may be more vulnerable to exploitation attempts. Additionally, the vulnerability could be leveraged as a foothold for further lateral movement within networks, amplifying its impact.

1. Immediately restrict access to the /intern/admin/edit_admin.php endpoint to trusted administrative users only, using network-level controls such as VPNs or IP whitelisting. 2. Implement strict input validation and sanitization on the admin_id parameter to prevent injection of malicious SQL code, employing parameterized queries or prepared statements. 3. Monitor logs for unusual or unauthorized access attempts targeting the admin_id parameter or the affected file. 4. Conduct a thorough code review of the membership management system to identify and remediate other potential injection points. 5. If available, apply official patches or updates from the vendor promptly; if not, consider isolating or replacing the vulnerable system. 6. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this vulnerability. 7. Educate administrative users on security best practices and enforce strong authentication mechanisms to reduce the risk of privilege escalation. 8. Regularly back up membership data and test restoration procedures to mitigate potential data loss from exploitation.
