CVE-2026-7266: Pizzafy Ecommerce SQL Injection Flaw

CVE-2026-7266 Overview

A SQL Injection vulnerability has been identified in SourceCodester Pizzafy Ecommerce System version 1.0. The vulnerability exists in the save_order function within the /admin/ajax.php?action=save_order endpoint. An attacker can exploit this flaw by manipulating the ID argument to inject malicious SQL queries. This vulnerability can be exploited remotely by authenticated users, potentially allowing unauthorized access to sensitive database information, data manipulation, or further system compromise.

Critical Impact
Attackers can exploit this SQL Injection vulnerability to extract sensitive data from the database, modify or delete records, and potentially escalate their access within the application. The exploit is publicly available, increasing the risk of active exploitation.

Affected Products

SourceCodester Pizzafy Ecommerce System 1.0
Web applications using the vulnerable /admin/ajax.php endpoint
Systems with exposed save_order functionality

Technical Details for CVE-2026-7266

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs due to insufficient input validation in the save_order function. The application fails to properly sanitize user-supplied input for the ID parameter before incorporating it into SQL queries. This allows an attacker to inject arbitrary SQL commands that are then executed by the database server.

The vulnerability requires low privileges to exploit, meaning an authenticated user with basic access to the admin panel can leverage this flaw. The network-based attack vector means no physical access is required, and the attack can be executed without any user interaction.

Root Cause

The root cause of this vulnerability is the lack of parameterized queries or prepared statements in the save_order function within /admin/ajax.php. The application directly concatenates user input from the ID parameter into SQL query strings without proper escaping or validation. This classic SQL Injection pattern allows attackers to break out of the intended query context and inject malicious SQL code.

Attack Vector

The attack is executed remotely through network-based access to the vulnerable endpoint. An attacker with low-level privileges can craft malicious requests to the /admin/ajax.php?action=save_order endpoint, manipulating the ID parameter to include SQL injection payloads. The vulnerability does not require user interaction and can be exploited directly against the affected system. According to available references, the exploit has been publicly documented, which increases the likelihood of opportunistic attacks against unpatched systems.

Detection Methods for CVE-2026-7266

Indicators of Compromise

Unusual or malformed requests to /admin/ajax.php?action=save_order containing SQL syntax characters such as single quotes, double dashes, or UNION statements
Database error messages appearing in application logs or responses indicating SQL syntax errors
Abnormal database query patterns or unauthorized data access attempts in database audit logs
Unexpected changes to order records or database entries without corresponding legitimate user actions

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the save_order endpoint
Monitor HTTP request logs for suspicious payloads containing SQL keywords (UNION, SELECT, INSERT, UPDATE, DELETE, DROP) in the ID parameter
Enable database query logging and alert on queries with unusual patterns or syntax errors originating from the web application
Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

Configure real-time alerting for any requests to /admin/ajax.php containing special characters or SQL keywords in parameters
Establish baseline metrics for normal database query patterns and alert on anomalies
Implement application-level logging to track all parameter values submitted to the save_order function
Regularly review access logs for the admin panel to identify unauthorized access attempts

How to Mitigate CVE-2026-7266

Immediate Actions Required

Restrict access to the admin panel (/admin/) to trusted IP addresses only until a patch is applied
Implement input validation on the ID parameter to accept only expected numeric values
Deploy a Web Application Firewall with SQL injection protection rules enabled
Review and audit all recent order modifications for signs of unauthorized tampering
Consider temporarily disabling the save_order functionality if not critical to operations

Patch Information

At the time of publication, no official vendor patch has been released for SourceCodester Pizzafy Ecommerce System 1.0. Organizations using this software should monitor SourceCodester for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.

For additional vulnerability information, consult VulDB Submission #802440 and VulDB CTI for #359917.

Workarounds

Modify the save_order function in /admin/ajax.php to use prepared statements or parameterized queries for all database operations
Implement server-side input validation to ensure the ID parameter contains only numeric values using functions like intval() or type casting
Add Web Application Firewall rules to filter requests containing SQL injection patterns targeting the vulnerable endpoint
Enforce strict access controls on the admin panel, limiting access to essential personnel only

bash

# Configuration example - Apache .htaccess to restrict admin access
<Directory "/var/www/html/admin">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Directory>

# Alternative: Block suspicious patterns in requests
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|;|--) [NC]
RewriteRule ^admin/ajax\.php$ - [F,L]
