CVE-2026-2176 identifies a SQL injection vulnerability in the code-projects Contact Management System version 1.0. The vulnerability arises from improper handling of the selecteditem[0] argument in the index.py file, which allows an attacker to inject malicious SQL code remotely. This injection flaw can be exploited without user interaction and requires only low privileges, indicating that an authenticated user with minimal rights could trigger the attack. The vulnerability impacts the confidentiality, integrity, and availability of the backend database, though the impact is considered limited (low) in each category. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). No patches or known exploits are currently available, which suggests that the vulnerability is newly disclosed and unmitigated. The lack of CWE classification limits detailed understanding of the root cause, but the injection point is clearly identified. This vulnerability could allow attackers to extract sensitive contact data, modify records, or disrupt service by manipulating SQL queries. Given the nature of contact management systems, the exposure of personal or business contact information could have significant privacy and operational consequences.

The vulnerability allows remote attackers to perform SQL injection attacks, potentially leading to unauthorized access to sensitive contact information stored in the database. This can compromise confidentiality by exposing personal or business data. Integrity may be affected if attackers modify or delete records, undermining trust in the system's data. Availability could be impacted if malicious queries cause database errors or crashes. Organizations relying on this Contact Management System may face data breaches, regulatory compliance issues, and operational disruptions. The medium CVSS score reflects that while exploitation is feasible and impactful, the overall damage is somewhat limited by the requirement for low privileges and the partial impact on security properties. However, in environments where this system manages critical contact data, the consequences could be severe, including reputational damage and financial loss.

Organizations should immediately review and sanitize all inputs related to selecteditem[0] in the index.py file to prevent SQL injection. Implement parameterized queries or prepared statements to ensure user inputs cannot alter SQL commands. Restrict access to the vulnerable endpoint to trusted users and networks, employing network segmentation and firewall rules. Monitor logs for suspicious query patterns indicative of injection attempts. Conduct a thorough code audit of the Contact Management System to identify and remediate similar injection points. If possible, isolate the database with strict access controls and consider deploying web application firewalls (WAFs) with SQL injection detection capabilities. Since no official patch is available, consider temporary mitigations such as disabling or restricting the vulnerable functionality until a fix is released. Educate developers and administrators on secure coding practices to prevent future injection flaws.
