CVE-2026-5019 Overview
A SQL Injection vulnerability has been identified in Carmelo Simple Food Order System version 1.0. The vulnerability exists within the all-orders.php file, specifically in the Parameter Handler component. Improper sanitization of the Status argument allows attackers to inject malicious SQL statements, potentially compromising the database integrity and exposing sensitive information.
Critical Impact
This SQL Injection vulnerability allows unauthenticated remote attackers to manipulate database queries through the Status parameter, potentially leading to unauthorized data access, modification, or deletion of order records.
Affected Products
- Carmelo Simple Food Order System 1.0
- Component: all-orders.php Parameter Handler

Technical Details for CVE-2026-5019
Vulnerability Analysis
This vulnerability stems from improper input validation in the all-orders.php file of the Simple Food Order System. The application fails to properly sanitize user-supplied input through the Status parameter before incorporating it into SQL queries. This classic SQL Injection (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) allows attackers to manipulate the underlying database queries.
The exploit has been publicly disclosed and may be actively used. The vulnerability is remotely exploitable without requiring authentication, making it accessible to any attacker who can reach the application over the network.
Root Cause
The root cause is insufficient input validation and lack of parameterized queries in the Parameter Handler component. When user input from the Status parameter is directly concatenated into SQL queries without proper escaping or prepared statements, it creates an injection point that attackers can exploit to execute arbitrary SQL commands.
Attack Vector
The attack is network-based and requires no authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the Status parameter of the all-orders.php endpoint. The vulnerability allows for low-impact confidentiality, integrity, and availability breaches, enabling attackers to read, modify, or potentially delete data from the application's database.
The exploit has been publicly documented. For detailed technical information, see the GitHub CVE Issue #17 and VulDB Vulnerability #353904.
Detection Methods for CVE-2026-5019
Indicators of Compromise
- Unusual SQL syntax patterns in HTTP request parameters targeting all-orders.php
- Anomalous database query logs showing unexpected SQL commands or UNION-based queries
- HTTP requests containing SQL keywords (SELECT, UNION, INSERT, DROP) in the Status parameter
- Database errors or timeout patterns indicating SQL injection attempts
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the Status parameter
- Monitor application logs for requests to all-orders.php containing suspicious characters such as single quotes, double dashes, or semicolons
- Deploy database activity monitoring to identify unusual query patterns or unauthorized data access
- Utilize intrusion detection systems (IDS) with SQL injection signature detection
Monitoring Recommendations
- Enable detailed logging for all requests to the all-orders.php endpoint
- Configure alerts for database errors that may indicate injection attempts
- Monitor for unusual data exfiltration patterns from the orders database
- Review web server access logs for repeated requests with varying Status parameter values
How to Mitigate CVE-2026-5019
Immediate Actions Required
- Restrict access to the all-orders.php endpoint until a patch is applied
- Implement input validation and sanitization for the Status parameter at the application level
- Deploy Web Application Firewall rules to block common SQL injection patterns
- Review and audit all database queries in the application for similar injection points
Patch Information
No official vendor patch has been released at this time. Organizations using Carmelo Simple Food Order System 1.0 should monitor the Code Projects website and GitHub CVE Issue #17 for updates on remediation guidance.
Workarounds
- Implement prepared statements or parameterized queries for all database interactions in all-orders.php
- Add server-side input validation to whitelist only expected Status parameter values
- Deploy a reverse proxy or WAF with SQL injection detection capabilities in front of the application
- Consider temporarily disabling or restricting access to the order status functionality until proper fixes can be implemented
# Example WAF rule to block SQL injection patterns (ModSecurity)
SecRule ARGS:Status "@rx (?i:(\%27)|(\')|(\-\-)|(\%23)|(#)|(\%3D)|(=))" \
"id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected in Status Parameter'"
