Published: 08 March 2026
Summary
CVE-2026-3723 is a medium-severity Injection (CWE-74) vulnerability in Carmelo Simple Flight Ticket Booking System. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.7th 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 SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-3723 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Simple Flight Ticket Booking System version 1.0. The issue resides in an unknown function within the file /Admindelete.php, where manipulation of the flightno argument enables injection attacks.
The vulnerability is remotely exploitable (AV:N) by unauthenticated attackers (PR:N) with low attack complexity (AC:L) and no requirement for user interaction (UI:N), resulting in unchanged scope (S:U) and low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). This yields a CVSS 3.1 base score of 7.3. An exploit has been publicly released, facilitating attacks.
Advisories referenced in VulDB entries (ctiid.349699, id.349699, submit.766311) and a GitHub issue (github.com/Owen-YuanW/CVE/issues/6) document the flaw, alongside the project site at code-projects.org. No specific patches or mitigations are detailed in the available information.
