CVE-2026-7224: SQL Injection in Pizzafy Ecommerce System Cart Deletion
A SQL injection vulnerability assigned CVE-2026-7224 has been disclosed in SourceCodester Pizzafy Ecommerce System 1.0, a PHP-based food ecommerce application. The vulnerability exists in the delete_cart function of the administrative AJAX handler and can be exploited remotely without advanced privileges to manipulate the backend database.
The flaw carries a CVSS v3.1 score of 7.3 (High) and is classified under CWE-89 — Improper Neutralization of Special Elements used in SQL Commands (SQL Injection).

Technical Details
Affected Component
The vulnerability is located in the cart management AJAX handler at /admin/ajax.php. When the action parameter is set to delete_cart, the ID parameter — which identifies the cart entry to be deleted — is passed directly into a SQL DELETE or SELECT query without sanitization or parameterization.
Exploitation Mechanism
An attacker with access to the AJAX endpoint can inject SQL syntax via the ID parameter:
POST /admin/ajax.php HTTP/1.1
Content-Type: application/x-www-form-urlencoded
action=delete_cart&ID=1' OR '1'='1
Or for a UNION-based extraction attack:
action=delete_cart&ID=1 UNION SELECT NULL,table_name,NULL,NULL FROM information_schema.tables--
Successful exploitation enables:
- Database enumeration — listing all tables, columns, and schemas
- Order data extraction — dumping customer orders, cart contents, and product records
- Credential exposure — harvesting hashed admin passwords from the users table
- Customer PII theft — extracting names, addresses, and payment-related records stored by the application
- Data manipulation — modifying or deleting cart and order records
Root Cause
The vulnerability stems from direct concatenation of user-supplied input into SQL query strings without using prepared statements or parameterized queries — a classic and well-understood implementation error that persists across many SourceCodester-distributed PHP applications.
Attack Flow
1. Attacker identifies a publicly accessible Pizzafy Ecommerce System instance
2. Attacker crafts a POST request to /admin/ajax.php with action=delete_cart
3. Attacker injects SQL payloads into the ID parameter
4. The application executes the injected SQL against the backend MySQL database
5. Attacker enumerates database structure, extracting table and column names
6. Attacker exfiltrates customer PII, order history, and admin credentials
7. With admin credentials, attacker gains full control of the ecommerce platform
Broader Impact: Ecommerce Data at Risk
Ecommerce systems like Pizzafy handle sensitive data categories that make SQL injection particularly damaging:
- Customer PII — names, email addresses, phone numbers, delivery addresses
- Order records — purchase history, item details, pricing information
- Admin credentials — hashed passwords enabling full application takeover
- Payment adjacency — while card data may be handled by a payment gateway, order metadata and contact data are stored locally
A successful exploitation of this vulnerability could result in a customer data breach with potential regulatory implications under GDPR, PIPEDA, or other applicable data protection frameworks.
Remediation
No official patch has been released by SourceCodester. Organizations running any version of Pizzafy Ecommerce System should take the following steps immediately:
Access Restriction
- Remove public access to the
/admin/directory — restrict it to known IP addresses via.htaccessor firewall rules - Require authentication for all AJAX endpoints — ensure
ajax.phpvalidates session state before processing any action - Deploy a WAF with SQL injection signatures in front of the application as a temporary compensating control
Input Validation
Replace direct string concatenation with prepared statements in the delete_cart handler:
// Vulnerable pattern
$query = "DELETE FROM cart WHERE id = " . $_POST['ID'];
mysqli_query($conn, $query);
// Secure pattern
$stmt = $conn->prepare("DELETE FROM cart WHERE id = ?");
$stmt->bind_param("i", $_POST['ID']);
$stmt->execute();Apply the same pattern to all other AJAX action handlers in ajax.php.
Detection
Review web server access logs for SQL injection patterns targeting the cart endpoint:
grep "delete_cart" /var/log/apache2/access.log | grep -i "union\|select\|insert\|drop\|--\|'"Impact Assessment
| Impact Area | Description |
|---|---|
| Customer PII Exposure | Names, addresses, and contact data accessible via injection |
| Order Data Theft | Full order history and cart contents extractable |
| Admin Credential Theft | Password hashes extractable, enabling full account takeover |
| Ecommerce Integrity | Orders and cart records can be modified or deleted |
| Exploit Availability | Public PoC lowers exploitation barrier significantly |
Key Takeaways
- CVE-2026-7224 is a CVSS 7.3 SQL injection in SourceCodester Pizzafy Ecommerce System 1.0, affecting the
/admin/ajax.phpdelete_cartaction - The
IDparameter is passed unsanitized into SQL queries, enabling remote data extraction and manipulation - SourceCodester applications have a well-documented history of similar SQL injection vulnerabilities across multiple products, indicating a systemic code quality issue
- No patch is available — restrict admin panel access and apply parameterized queries immediately if this software is in use
- Operators should also audit all other action handlers in
ajax.phpfor the same unsanitized input pattern
