Summary
CVE-2026-2176 is a medium-severity Injection (CWE-74) vulnerability in Fabian Contact Management System. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 15.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-2176 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Contact Management System 1.0. The issue affects unknown processing logic in the index.py file, where manipulation of the selecteditem[0] argument enables SQL code injection. The vulnerability has a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), indicating medium severity with network accessibility and low attack complexity.
A remote attacker with low privileges, such as an authenticated user, can exploit this vulnerability without requiring user interaction. Exploitation over the network allows limited impacts, including partial disclosure of confidential information, limited data modification, and limited denial-of-service effects through resource consumption.
