CVE-2026-3736
Published: 08 March 2026
Summary
CVE-2026-3736 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 26.2th 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-2026-3736 is a SQL injection vulnerability in code-projects Simple Flight Ticket Booking System version 1.0. The issue affects an unknown functionality within the file SearchResultRoundtrip.php, where manipulation of the "from results" argument triggers the injection. It has been assigned CWE-74 and CWE-89, with 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 low complexity.
Remote attackers require no privileges or user interaction to exploit this vulnerability over the network. By crafting malicious input for the affected argument, they can execute arbitrary SQL queries, potentially leading to limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or denial of service within the application's database.
Advisories documented on VulDB (ctiid.349714, id.349714, submit.768093) and a GitHub issue (6Justdododo6/CVE/issues/12) detail the vulnerability, while the original project site is at code-projects.org. No specific patches or mitigation steps are outlined in the available information; practitioners should review these references for updates and apply input sanitization or upgrades where possible.
The exploit has been made public and could be used, increasing the risk for unpatched instances of the software.

Why these techniques?
SQL injection in a network-accessible web app (SearchResultRoundtrip.php) directly enables remote exploitation of a public-facing application (T1190). Arbitrary SQL queries also directly facilitate collection of data from the application's database (T1213.006).

Directly requires validation and sanitization of untrusted inputs such as the 'from results' argument in SearchResultRoundtrip.php to block SQL injection payloads.
Limits the privileges of the database account used by the application so that a successful SQL injection cannot read, modify, or affect data beyond the minimum required scope.
Enables monitoring of database queries and web-application inputs to identify anomalous SQL statements originating from the vulnerable SearchResultRoundtrip.php endpoint.
