CVE-2026-6149 Overview
A SQL injection vulnerability has been discovered in code-projects Vehicle Showroom Management System 1.0. The flaw exists in the file /util/BookVehicleFunction.php where the BRANCH_ID argument is not properly sanitized before being used in SQL queries. This allows remote attackers to manipulate database queries by injecting malicious SQL code through the vulnerable parameter.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system without authentication.

Technical Details for CVE-2026-6149
Vulnerability Analysis
This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as injection. The flaw resides in the BookVehicleFunction.php file within the Vehicle Showroom Management System application. The vulnerable endpoint fails to properly validate and sanitize the BRANCH_ID parameter before incorporating it into SQL queries executed against the backend database.
The network-accessible nature of this vulnerability means that attackers do not require any prior authentication or special privileges to exploit it. The attack can be initiated remotely through standard HTTP requests to the affected PHP file, making it particularly dangerous in internet-facing deployments.
Root Cause
The root cause of this vulnerability is improper input validation and the lack of parameterized queries or prepared statements in the BookVehicleFunction.php file. When user-supplied input from the BRANCH_ID parameter is directly concatenated into SQL statements without proper sanitization, it creates an injection point that attackers can leverage to manipulate the query logic.
This type of vulnerability typically occurs when developers trust user input and fail to implement proper security controls such as input validation, output encoding, or parameterized database queries.
Attack Vector
The attack vector for CVE-2026-6149 is network-based, requiring no user interaction or authentication. An attacker can craft malicious HTTP requests containing SQL injection payloads in the BRANCH_ID parameter and send them directly to the vulnerable /util/BookVehicleFunction.php endpoint.
The exploitation process involves injecting SQL syntax that modifies the intended query behavior. This could include UNION-based injection to extract data from other tables, boolean-based blind injection for data exfiltration, or time-based blind injection techniques. The public availability of exploit information, as noted in the GitHub CVE Issue Report, increases the risk of active exploitation.
Detection Methods for CVE-2026-6149
Indicators of Compromise
- HTTP requests to /util/BookVehicleFunction.php containing SQL syntax in the BRANCH_ID parameter such as single quotes, UNION statements, or comment sequences
- Database error messages in application logs indicating malformed SQL queries
- Unusual database query patterns or increased database load from web application connections
- Access logs showing repeated requests to the vulnerable endpoint with varying payloads
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the BRANCH_ID parameter
- Implement intrusion detection system (IDS) signatures for SQL injection attack patterns targeting PHP applications
- Enable detailed logging for database queries and monitor for anomalous query structures
- Configure application-level logging to capture requests to /util/BookVehicleFunction.php
Monitoring Recommendations
- Establish baseline traffic patterns for the affected endpoint and alert on deviations
- Monitor database audit logs for unauthorized data access or modification attempts
- Set up real-time alerting for multiple failed or malformed requests to the vulnerable file
- Review web server access logs regularly for reconnaissance activity targeting the application
How to Mitigate CVE-2026-6149
Immediate Actions Required
- Restrict access to /util/BookVehicleFunction.php through web server configuration or firewall rules until a patch is applied
- Implement input validation to reject non-numeric or unexpected values in the BRANCH_ID parameter
- Deploy WAF rules specifically targeting SQL injection in the affected parameter
- Consider taking the Vehicle Showroom Management System offline if it processes sensitive data
Patch Information
At the time of publication, no official patch has been released by code-projects for this vulnerability. Users should monitor the Code Projects Security Overview for security updates. Additional technical details and community discussion can be found in the VulDB Vulnerability #357029 entry and the GitHub CVE Issue Report.
Workarounds
- Modify the vulnerable PHP code to use prepared statements with parameterized queries for all database interactions involving the BRANCH_ID parameter
- Implement server-side input validation to ensure BRANCH_ID only accepts expected integer values
- Use a Web Application Firewall to filter malicious SQL injection attempts before they reach the application
- Restrict network access to the application to trusted IP addresses only using firewall rules
