Deeper analysis

CVE-2026-3705 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Simple Flight Ticket Booking System 1.0. The issue affects the processing of the /Adminsearch.php file, where manipulation of the 'flightno' argument enables SQL injection.

The vulnerability is remotely exploitable with low complexity and no privileges required, per its CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Unauthenticated attackers can inject SQL payloads to achieve limited impacts on confidentiality, integrity, and availability. An exploit has been made public and could be used.

Advisories referenced in VulDB entries (ctiid.349651, id.349651, submit.765797) and a GitHub issue (Owen-YuanW/CVE/issues/1) document the flaw, with the project page at code-projects.org. No specific patches are detailed in available information.
