Deeper analysisAI
CVE-2026-3709 is a SQL injection vulnerability in code-projects Simple Flight Ticket Booking System 1.0. The issue affects an unknown function in the /register.php file, where manipulation of the Username argument enables the injection. Associated with CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and lack of prerequisites.
The vulnerability can be exploited remotely by unauthenticated attackers with low complexity, requiring no user interaction or privileges. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling data extraction, modification, or disruption within the application's database. An exploit is publicly available, increasing the risk of real-world attacks against exposed instances.
Advisories and further details are available in references such as VulDB entries (ctiid.349655, id.349655, submit.766142), a GitHub issue at github.com/Owen-YuanW/CVE/issues/3, and the project site at code-projects.org, which may provide mitigation guidance or patches, though specifics are not detailed here.
Notably, the public exploit availability heightens the urgency for practitioners to scan and patch deployments of this booking system.
