CVE-2026-0697 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0. The vulnerability resides in the /intern/admin/edit_admin.php file, where the admin_id parameter is improperly sanitized, allowing an attacker to inject malicious SQL commands. This flaw can be exploited remotely without user interaction, but requires high privileges (likely administrative access) to trigger. The injection can lead to unauthorized data access, modification, or deletion, compromising the confidentiality, integrity, and availability of the membership management system's database. The vulnerability has been assigned a CVSS 4.0 score of 5.1, indicating medium severity, primarily because exploitation requires privileged access but no user interaction or complex attack vectors. Although no active exploitation has been reported, the availability of exploit code increases the risk of future attacks. The lack of official patches or mitigations at the time of disclosure necessitates immediate defensive measures by system administrators. The vulnerability highlights the importance of secure coding practices such as input validation and use of parameterized queries to prevent SQL injection attacks.

The SQL injection vulnerability in the Intern Membership Management System can have significant impacts on organizations using this software. Attackers with high privileges can exploit the flaw to execute arbitrary SQL commands, potentially leading to unauthorized disclosure of sensitive membership data, modification or deletion of records, and disruption of system availability. This can result in data breaches, loss of trust, regulatory penalties, and operational downtime. Since the system manages membership information, the exposure of personally identifiable information (PII) or internal administrative data could have privacy and compliance implications. The remote exploitability without user interaction increases the risk of automated attacks once exploit code becomes widespread. Organizations relying on this system for critical membership management functions may face operational and reputational damage if the vulnerability is exploited.

To mitigate CVE-2026-0697, organizations should implement the following specific measures: 1) Immediately restrict access to the /intern/admin/edit_admin.php endpoint to trusted administrators only, using network segmentation and access control lists. 2) Apply strict input validation and sanitization on the admin_id parameter to ensure only expected numeric or alphanumeric values are accepted. 3) Refactor the vulnerable code to use parameterized SQL queries or prepared statements to eliminate injection vectors. 4) Monitor logs for unusual SQL errors or suspicious activity targeting the admin_id parameter. 5) If possible, upgrade to a patched version once available or apply vendor-provided patches promptly. 6) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. 7) Conduct regular security assessments and code reviews focusing on input handling in administrative modules. 8) Educate administrators on the risks of SQL injection and the importance of secure credential management to prevent privilege escalation.
