CVE-2026-14713: Pizzafy E-Commerce System SQLi Vulnerability

CVE-2026-14713 Overview

CVE-2026-14713 is a SQL injection vulnerability in SourceCodester Pizzafy E-Commerce System 1.0. The flaw resides in the /admin/ajax.php?action=confirm_order endpoint, where the ID parameter is passed unsanitized into a database query. Remote attackers can manipulate the parameter to inject arbitrary SQL statements against the backend database.

The issue is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). A public exploit has been released, increasing the likelihood of opportunistic attacks against exposed installations.

Critical Impact
Remote unauthenticated attackers can inject SQL statements through the ID parameter, enabling data disclosure, tampering, and potential administrative compromise of the Pizzafy backend.

Technical Details for CVE-2026-14713

Vulnerability Analysis

The vulnerability exists in the administrative AJAX handler at /admin/ajax.php when invoked with the action=confirm_order parameter. The handler accepts an ID argument that identifies the order to confirm, but the value is concatenated directly into a SQL statement without parameterization or input validation.

An attacker supplying crafted input in the ID parameter can alter query logic, extract data through UNION-based or boolean-based techniques, and potentially execute time-based blind injection. Because the exploit has been publicly disclosed, adversaries can weaponize it with minimal effort.

Successful exploitation exposes the underlying MySQL database, including order records, customer information, and administrator credentials stored in application tables.

Root Cause

The root cause is missing input neutralization before the ID value is embedded in a dynamic SQL query. The application does not use prepared statements or parameterized queries, and it does not enforce type casting or whitelisting on the incoming parameter.

Attack Vector

The attack is delivered over the network against the administrative AJAX endpoint. No authentication or user interaction appears to be required to reach the vulnerable code path. An attacker sends an HTTP request to /admin/ajax.php?action=confirm_order with a malicious ID parameter containing SQL syntax. See the GitHub Issue on CVE and VulDB CVE-2026-14713 entry for reproduction details.

Detection Methods for CVE-2026-14713

Indicators of Compromise

HTTP requests to /admin/ajax.php?action=confirm_order containing SQL metacharacters such as single quotes, UNION SELECT, SLEEP(, or comment sequences (--, #) in the ID parameter.
Unusually long or URL-encoded payloads targeting the ID argument.
Database error messages returned in HTTP responses referencing MySQL syntax errors.
Spikes in requests to the confirm_order action from a single source IP.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the ID parameter of /admin/ajax.php?action=confirm_order for SQL syntax patterns.
Enable MySQL general query logging and alert on anomalous statements originating from the Pizzafy application user.
Correlate web access logs with database audit logs to identify parameter tampering.

Monitoring Recommendations

Monitor administrative endpoints for unauthenticated access attempts and log all requests to /admin/ajax.php.
Track outbound data volume from the database host to detect bulk extraction.
Review new or modified administrator accounts and unexpected privilege changes in the application schema.

How to Mitigate CVE-2026-14713

Immediate Actions Required

Restrict access to the /admin/ directory using network ACLs, VPN, or IP allow-listing until a patched version is available.
Deploy WAF signatures that block SQL injection payloads targeting the ID parameter of the confirm_order action.
Audit the pizzafy database for unauthorized changes, suspicious admin accounts, and evidence of data exfiltration.

Patch Information

No vendor patch has been published for SourceCodester Pizzafy E-Commerce System 1.0 at the time of NVD publication. Monitor the SourceCodester website and the VulDB advisory for updates. Until a fix is available, operators should refactor the vulnerable handler to use parameterized queries and enforce integer casting on the ID parameter.

Workarounds

Modify /admin/ajax.php to cast $_POST['ID'] or $_GET['ID'] to an integer before use in any query.
Replace dynamic query construction with PDO prepared statements or mysqli parameter binding.
Require authentication and CSRF tokens on all /admin/ajax.php actions.
Disable or remove the Pizzafy application from public-facing infrastructure if it is not business-critical.
