Summary
CVE-2026-3711 is a medium-severity Injection (CWE-74) vulnerability in Carmelo Simple Flight Ticket Booking System. Its CVSS base score is 5.1 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 17.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-3711 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Simple Flight Ticket Booking System 1.0, published on 2026-03-08. The issue affects an unknown function within the file /Adminupdate.php, where manipulation of arguments including flightno, airplaneid, departure, dtime, arrival, atime, ec, ep, bc, and bp enables SQL injection. The vulnerability has a CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L), indicating network accessibility with low complexity but requiring high privileges.
Attackers with high-level privileges, such as administrative access, can exploit this remotely by injecting malicious SQL payloads into the vulnerable parameters. Successful exploitation grants low impacts on confidentiality, integrity, and availability, potentially allowing limited data exposure, modification, or disruption within the application's database.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of inputs such as flightno/airplaneid/departure before they reach the SQL statements in Adminupdate.php, blocking the CWE-89 injection.
Limits the number of accounts that possess the high privileges needed to reach the vulnerable /Adminupdate.php endpoint, shrinking the attack surface.
Mandates timely application of patches or code fixes to the public SQL-injection flaw once a remediation becomes available.
