CVE-2026-3723
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA security flaw has been discovered in code-projects Simple Flight Ticket Booking System 1.0. This affects an unknown function of the file /Admindelete.php. The manipulation of the argument flightno results in sql injection. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in Simple Flight Ticket Booking System 1.0's Admindelete.php file allows remote attackers to inject malicious SQL queries via the 'flightno' parameter. The lack of input sanitization or parameterized queries enables attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or complete system compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed version of the Flight Ticket Booking SystemLocate and inspect any version files, headers, or metadata files in the application installation directory that indicate the software version. Check README files, changelogs, or the main index.php for version information.Affected if The installed version is exactly 1.0 of Carmelo Simple Flight Ticket Booking System
-
Verify Admindelete.php exists in the applicationSearch the web root directory for the file Admindelete.php. Common locations may include /admin/, /php/, or the root web directory. Use file system search or check the application's file structure.Affected if The file Admindelete.php is present in the application installation
-
Check if the flightno parameter is processed unsafelyOpen Admindelete.php and inspect the code handling the 'flightno' parameter. Look for direct insertion of the parameter into SQL queries without using prepared statements, parameter binding, or input sanitization functions.Affected if The code shows direct use of $_GET['flightno'] or $_POST['flightno'] concatenated into SQL queries without escaping or parameterized queries
-
Confirm the vulnerable endpoint is accessibleAttempt to access Admindelete.php via HTTP/HTTPS request (e.g., GET or POST to the file URL with a test flightno parameter). Verify the application responds and the parameter is processed.Affected if The Admindelete.php endpoint is reachable and processes the flightno parameter without validation
A system is affected if it runs Simple Flight Ticket Booking System version 1.0 AND contains the Admindelete.php file with the unprotected flightno parameter that gets inserted directly into SQL queries.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with parameterized queries/prepared statements in Admindelete.php, apply input validation on the flightno parameter, and conduct a broader security audit of the application for similar SQL injection vulnerabilities.
