CVE-2026-2176 identifies a SQL injection vulnerability in the code-projects Contact Management System version 1.0, specifically within the index.py file. The vulnerability stems from improper sanitization or validation of the selecteditem[0] parameter, which is processed in a way that allows attackers to inject arbitrary SQL commands. This injection flaw can be exploited remotely without requiring user interaction or elevated privileges, as indicated by the CVSS vector (AV:N/AC:L/PR:L/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the system, albeit with low scope and impact metrics, suggesting the affected components are limited in reach. Although no public exploits have been reported, the flaw could enable attackers to extract sensitive contact data, modify records, or disrupt service availability. The lack of available patches necessitates immediate attention from administrators. The vulnerability's medium severity rating (CVSS 5.3) reflects a moderate risk, balancing ease of exploitation with limited impact scope. The vulnerability is relevant to organizations relying on this specific contact management solution, particularly those handling sensitive or regulated data.

For European organizations, exploitation of CVE-2026-2176 could lead to unauthorized disclosure of personal and business contact information, violating data protection regulations such as GDPR. Integrity of contact records could be compromised, leading to misinformation or operational disruptions. Availability impacts could arise if attackers leverage the injection to cause database errors or denial of service. Organizations in sectors like finance, healthcare, and government, which often use contact management systems to handle sensitive data, face increased risk of reputational damage and regulatory penalties. The remote exploitability and lack of required user interaction increase the threat surface, making it easier for attackers to target exposed systems. Although the vulnerability affects a specific software version, the potential for lateral movement or pivoting within networks could amplify the impact if not contained.

Specific mitigation steps include: 1) Immediate code review and remediation of the index.py file to implement proper input validation and sanitization of the selecteditem[0] parameter. 2) Refactoring database queries to use parameterized statements or prepared queries to prevent injection. 3) Deploying Web Application Firewalls (WAFs) with rules targeting SQL injection patterns related to this parameter. 4) Monitoring database logs and application behavior for anomalous queries or access patterns. 5) Restricting database user permissions to the minimum necessary to limit potential damage from injection attacks. 6) If patching is not immediately possible, consider isolating the affected system from external network access or implementing strict network segmentation. 7) Conducting security awareness training for developers and administrators on secure coding practices. 8) Regularly updating and auditing third-party components to detect similar vulnerabilities early.
