CVE-2026-2136: Online Food Ordering System SQLi Flaw

CVE-2026-2136 Overview

A SQL injection vulnerability has been discovered in Projectworlds Online Food Ordering System version 1.0. The flaw exists in the /view-ticket.php file where the ID parameter is not properly sanitized before being used in database queries. This allows remote attackers to manipulate SQL queries by injecting malicious input through the ID argument, potentially compromising database integrity and confidentiality.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database records, or potentially gain unauthorized access to the underlying system through database manipulation techniques.

Technical Details for CVE-2026-2136

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists due to improper neutralization of special elements used in SQL commands within the /view-ticket.php endpoint. The application fails to properly validate or sanitize the ID parameter before incorporating it into SQL queries, allowing attackers to inject arbitrary SQL statements. This weakness falls under the broader category of injection flaws (CWE-74).

The vulnerability can be exploited remotely without authentication, requiring no user interaction. An attacker can manipulate the ID parameter to execute unauthorized database operations, potentially leading to data extraction, data modification, or further system compromise.

Root Cause

The root cause is improper input validation and failure to use parameterized queries or prepared statements when handling the ID parameter in /view-ticket.php. User-supplied input is directly concatenated into SQL query strings without proper sanitization or escaping, allowing SQL syntax to be injected and interpreted by the database engine.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can craft malicious HTTP requests to the /view-ticket.php endpoint with specially crafted ID parameter values containing SQL injection payloads. Common techniques include UNION-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based blind injection when direct output is not visible.

The vulnerability mechanism involves manipulating the ID parameter to break out of the intended SQL query context and inject additional SQL commands. For detailed technical analysis, refer to the GitHub CVE Issue Discussion and VulDB CTI Report #344771.

Detection Methods for CVE-2026-2136

Indicators of Compromise

• Unusual HTTP requests to /view-ticket.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences like -- and /*
• Database error messages in application logs indicating malformed SQL queries or syntax errors
• Anomalous database query patterns showing unexpected data access or enumeration attempts
• Web application logs showing multiple requests with varying ID parameter values testing for injection points

Detection Strategies

• Deploy Web Application Firewalls (WAF) with SQL injection detection rules to identify and block malicious payloads targeting the ID parameter
• Implement application-layer intrusion detection to monitor for SQL injection attack patterns in HTTP request parameters
• Enable verbose database query logging to detect unauthorized or anomalous SQL statements
• Use SentinelOne Singularity Platform to monitor endpoint behavior for post-exploitation activities following successful SQL injection

Monitoring Recommendations

• Configure real-time alerts for SQL error messages appearing in web server and application logs
• Monitor database activity for unusual query patterns, especially bulk data extraction or unauthorized table access
• Implement rate limiting on the /view-ticket.php endpoint to slow automated injection attempts
• Review access logs for repeated requests with encoded or obfuscated parameter values

How to Mitigate CVE-2026-2136

Immediate Actions Required

• Restrict access to /view-ticket.php or take the affected Online Food Ordering System offline until a patch is available
• Deploy WAF rules to filter SQL injection attempts targeting the ID parameter
• Implement input validation at the application layer to accept only numeric values for the ID parameter
• Review and audit database access logs for signs of prior exploitation

Patch Information

No official vendor patch is currently available for this vulnerability. Monitor the GitHub CVE Issue Discussion and vendor channels for updates. Organizations using this software should consider implementing temporary mitigations or migrating to an alternative solution until a fix is released.

Workarounds

• Modify the application code to use parameterized queries or prepared statements for all database operations involving user input
• Implement strict input validation to ensure the ID parameter contains only expected numeric characters
• Deploy a reverse proxy or WAF configured to sanitize or block requests containing SQL injection patterns
• Limit database user privileges to the minimum required for application functionality, reducing potential impact of successful exploitation

# Example WAF rule for ModSecurity to block SQL injection attempts
