CVE-2026-7226: Pizzafy Ecommerce System SQLi Vulnerability

CVE-2026-7226 Overview

A SQL injection vulnerability has been discovered in SourceCodester Pizzafy Ecommerce System version 1.0. This vulnerability affects the login2 function within the file /admin/ajax.php?action=login2. The flaw allows attackers to manipulate the e-mail parameter to inject malicious SQL statements, potentially compromising the underlying database. Remote exploitation of this vulnerability is possible, and the exploit has been disclosed publicly.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data from the database, or potentially modify/delete records on the affected ecommerce system.

Technical Details for CVE-2026-7226

Vulnerability Analysis

This SQL injection vulnerability exists in the administrative login functionality of the Pizzafy Ecommerce System. The login2 function fails to properly sanitize user-supplied input in the e-mail parameter before incorporating it into SQL queries. This lack of input validation allows attackers to craft malicious payloads that can manipulate the database query logic.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user input is not properly validated before being used in commands or queries.

Root Cause

The root cause of this vulnerability is insufficient input sanitization in the login2 function. The application directly incorporates user-supplied email parameter values into SQL queries without using parameterized queries, prepared statements, or proper input validation. This allows special characters and SQL syntax to be interpreted as part of the query rather than as literal data.

Attack Vector

The attack is network-accessible, requiring no authentication or user interaction. An attacker can send specially crafted HTTP requests to the /admin/ajax.php?action=login2 endpoint with malicious SQL payloads in the e-mail parameter. This could allow the attacker to:

• Bypass authentication mechanisms
• Extract sensitive information from the database including user credentials
• Modify or delete database records
• Potentially escalate to further system compromise depending on database configuration

The vulnerability is triggered through the email parameter of the login form. An attacker submits a crafted payload containing SQL syntax that alters the intended query logic. When the application processes this input without proper sanitization, the injected SQL commands are executed against the database.

Detection Methods for CVE-2026-7226

Indicators of Compromise

• Unusual HTTP POST requests to /admin/ajax.php?action=login2 containing SQL syntax characters such as single quotes, semicolons, or SQL keywords in the e-mail parameter
• Database error messages in application logs indicating malformed SQL queries
• Failed login attempts with abnormally long or unusual email field values
• Unexpected database query patterns or access to tables outside normal application behavior

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in request parameters targeting the admin login endpoint
• Implement application logging to capture all authentication attempts and flag those containing special characters or SQL keywords
• Monitor database query logs for anomalous queries originating from the web application
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging on the web server for all requests to /admin/ajax.php
• Configure database auditing to track queries executed by the application database user
• Set up alerts for multiple failed login attempts from the same IP address
• Monitor for any unauthorized data exfiltration or unusual outbound traffic from the database server

How to Mitigate CVE-2026-7226

Immediate Actions Required

• Restrict network access to the administrative interface to trusted IP addresses only
• Consider taking the affected admin login functionality offline until a patch can be applied
• Implement a Web Application Firewall with SQL injection protection rules as a temporary measure
• Review application and database logs for signs of prior exploitation

Patch Information

No official vendor patch has been identified in the available CVE data. Organizations using SourceCodester Pizzafy Ecommerce System 1.0 should monitor SourceCodester for security updates. Given the nature of SourceCodester projects (typically educational/demo code), users may need to implement fixes independently or consider using alternative, actively maintained ecommerce solutions.

• VulDB CTI for #359826

Workarounds

• Implement input validation on the e-mail parameter using server-side code to reject inputs containing SQL metacharacters
• Modify the login2 function to use parameterized queries or prepared statements instead of string concatenation
• Deploy a reverse proxy or WAF configured to filter SQL injection patterns before requests reach the application
• Restrict database user privileges to limit the impact of successful SQL injection attacks

# Example: Apache .htaccess rule to restrict admin access by IP
<Files "ajax.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
