CVE-2026-0701 is a SQL injection vulnerability identified in the code-projects Intern Membership Management System version 1.0. The flaw exists in the /intern/admin/add_admin.php script, where the Username parameter is not properly sanitized before being used in SQL queries. This allows an attacker to remotely inject arbitrary SQL code, potentially manipulating the backend database. The vulnerability does not require user interaction or authentication, increasing its risk profile. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H - high privileges required, but the vector states PR:H which conflicts with the description; assuming a typo in CVSS vector, likely PR:N or PR:L), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability could allow attackers to extract sensitive data, modify database contents, or disrupt service availability. Although no exploits are reported in the wild, public proof-of-concept code exists, facilitating potential exploitation. The affected product is niche but may be used by organizations managing intern or membership data, making the vulnerability relevant for sectors relying on such systems. The lack of available patches necessitates immediate mitigation through secure coding practices and access controls.

For European organizations using the affected Intern Membership Management System 1.0, this vulnerability poses a risk of unauthorized data access, data manipulation, and potential service disruption. Confidential membership or intern data could be exposed or altered, leading to privacy violations and operational impacts. The ability to exploit the vulnerability remotely without user interaction increases the threat level, especially for internet-facing administrative interfaces. This could lead to reputational damage, regulatory non-compliance (e.g., GDPR breaches), and financial losses. Organizations in sectors such as education, non-profits, or any entity managing intern memberships are particularly vulnerable. The medium CVSS score reflects moderate risk, but the presence of public exploit code could accelerate attacks. The impact is compounded if the system integrates with other critical infrastructure or contains sensitive personal data.

1. Immediately implement input validation and sanitization on the Username parameter to prevent SQL injection. 2. Refactor the vulnerable code to use parameterized queries or prepared statements instead of dynamic SQL concatenation. 3. Restrict access to the /intern/admin/add_admin.php endpoint using network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure. 4. Conduct a thorough code review of the entire application to identify and remediate similar injection flaws. 5. Monitor logs for suspicious SQL queries or unusual access patterns targeting the admin interface. 6. If possible, upgrade to a patched version once available or consider migrating to a more secure membership management system. 7. Educate developers on secure coding practices to prevent future injection vulnerabilities. 8. Apply web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this system.
