CVE-2026-14713 — SQL Injection in SourceCodester Pizzafy E-Commerce System

A significant security flaw, tracked as CVE-2026-14713, has been identified in the SourceCodester Pizzafy E-Commerce System 1.0. This vulnerability manifests as a remote SQL injection within the /admin/ajax.php file, specifically when handling the ID argument in the action=confirm_order context. Threat actors can exploit this by crafting malicious HTTP requests that embed SQL queries into the ID parameter. The flaw allows for unauthenticated remote exploitation, meaning attackers can leverage it without prior access to the system. The existence of a public exploit for this vulnerability elevates the immediate risk, making it critical for organizations using this software to patch or implement protective measures swiftly to prevent potential data breaches, unauthorized data manipulation, or system compromise.

Attack Chain

1. Attacker identifies a publicly accessible instance of SourceCodester Pizzafy E-Commerce System 1.0.
2. Attacker crafts a specially designed HTTP GET request targeting the /admin/ajax.php endpoint.
3. The request includes the action=confirm_order parameter and a malicious SQL payload embedded within the ID argument (e.g., ID=1 UNION SELECT @@version, user(), database()).
4. The vulnerable application processes this request, failing to properly sanitize the ID parameter, and executes the attacker-supplied SQL query against its backend database.
5. The database management system (DBMS) processes the injected query and returns the results within the legitimate HTTP response from the web server.
6. Attacker parses the web server's response to extract sensitive information, such as database schema, user credentials, system configuration, or other confidential data.
7. The attacker continues to refine payloads to further exfiltrate, modify, or potentially corrupt data within the database, ultimately achieving data compromise.

Impact

Successful exploitation of CVE-2026-14713 can lead to severe consequences for organizations utilizing SourceCodester Pizzafy E-Commerce System 1.0. As a remote SQL injection vulnerability, attackers can gain unauthorized access to the underlying database. This typically results in full data compromise, including exfiltration of sensitive customer data (names, addresses, payment information), administrative credentials, and other proprietary business data. Attackers could also tamper with order details, pricing, inventory, or user accounts, causing financial losses, reputational damage, and operational disruption. While the source does not specify victim count or targeted sectors, any organization deploying this specific version of the e-commerce system is at high risk.
