CVE-2026-3735: Php

Overview

A high-severity SQL injection vulnerability, tracked as CVE-2026-3735, has been discovered in the code-projects Simple Flight Ticket Booking System version 1.0. This flaw allows remote attackers to execute malicious SQL commands on the application’s database.

Vulnerability Details

The vulnerability exists in the SearchResultOneway.php file. Specifically, the from parameter is not properly sanitized before being used in a database query. An attacker can craft a malicious request containing SQL code within this parameter. Because the system does not validate or “clean” this input, the database will execute the attacker’s code as if it were a legitimate command. This type of flaw is a classic and dangerous form of SQL injection.

Impact and Risk

With a CVSS score of 7.3 (HIGH), this vulnerability poses a significant risk. A successful attack could allow an unauthenticated, remote attacker to:

• Steal sensitive data from the database, including customer information, booking details, and administrative credentials.
• Modify or delete data, corrupting the booking system’s functionality.
• Potentially gain further access to the underlying server.

The exploit for this vulnerability is already publicly disclosed, making active attacks highly likely. Organizations using the affected software are at immediate risk of data breaches. For more on the consequences of such incidents, recent data breach reports are available at breach reports.

Remediation and Mitigation

As this is a vulnerability in a specific version of a software project, the primary remediation path is to apply a fix from the vendor.

1. Apply an Official Patch: Immediately contact the software vendor (code-projects) to obtain a patched version of the Simple Flight Ticket Booking System. Replace all instances of version 1.0 with the updated, secure version.
2. Temporary Mitigation: If an immediate patch is not available, you can implement a Web Application Firewall (WAF) configured with rules to block SQL injection patterns. This can help filter malicious requests but is not a substitute for a proper code fix.
3. General Best Practice: This incident underscores the need for secure coding practices, specifically input validation and the use of parameterized queries (prepared statements) to prevent SQL injection. For ongoing updates on such threats, follow the latest security news.

Action Required: Administrators of the Simple Flight Ticket Booking System 1.0 must treat this as an urgent priority. Verify your version and seek a vendor update immediately to protect your system and user data from compromise.
