CVE-2026-78199: Online Food Ordering System SQLI Flaw

CVE-2026-78199 is a SQL injection vulnerability in SourceCodester Simple Online Food Ordering System 1.0 affecting the view_prod.php file. Attackers can exploit this remotely to manipulate databases. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2026-78199 Overview

CVE-2026-78199 is a SQL injection vulnerability in SourceCodester Simple Online Food Ordering System 1.0. The flaw resides in the /fos/view_prod.php script, where the ID parameter is passed to a backend database query without proper sanitization. Remote attackers can manipulate the ID argument to inject arbitrary SQL statements. Public exploit details have been disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The weakness is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.

Critical Impact
Unauthenticated remote attackers can read, modify, or exfiltrate database contents through the ID parameter of view_prod.php, potentially exposing customer records and order data.

Affected Products

Technical Details for CVE-2026-78199

Vulnerability Analysis

The vulnerability affects the product view functionality of the Simple Online Food Ordering System. The script /fos/view_prod.php accepts an ID parameter through an HTTP request and concatenates it directly into a SQL statement. Because no parameterization or input validation is applied, an attacker can break out of the intended query context and append arbitrary SQL clauses.

Exploitation requires no authentication and no user interaction, and the attack is executable over the network. The public availability of exploit details lowers the barrier for attackers to weaponize the flaw against internet-facing storefronts.

Root Cause

The root cause is improper neutralization of user-controlled input passed to the SQL layer. The ID argument is treated as trusted data and inserted into a query string rather than bound as a parameter. This design pattern is a well-known anti-pattern that CWE-74 addresses and is typically resolved through prepared statements with bound parameters.

Attack Vector

An attacker sends a crafted HTTP GET or POST request to /fos/view_prod.php with a malicious ID value containing SQL metacharacters. Payloads may use UNION-based, boolean-based, or time-based techniques to extract rows from tables such as user accounts or order history. Because the application is a food ordering platform, exposed data commonly includes customer credentials, addresses, and order details.

No verified exploit code has been published in a controlled repository. See the GitHub Issue #5 and VulDB entry for CVE-2026-78199 for further technical context.

Detection Methods for CVE-2026-78199

Indicators of Compromise

HTTP requests to /fos/view_prod.php containing SQL metacharacters such as ', --, UNION SELECT, or SLEEP( in the ID parameter.
Web server logs showing unusually long or URL-encoded ID values from a single source address.
Database error messages or 500 responses correlated with requests to view_prod.php.

Detection Strategies

Deploy web application firewall (WAF) signatures that inspect the ID query parameter for SQL injection patterns.
Enable database query logging and alert on queries referencing unexpected tables from the food ordering application context.
Correlate access logs with authentication and order-processing telemetry to identify anomalous data enumeration.

Monitoring Recommendations

Monitor outbound data volume from the database server for signs of bulk extraction.
Track repeat requests to view_prod.php from single IPs over short intervals as a potential blind SQL injection indicator.
Alert on any process spawned by the PHP runtime that deviates from the application baseline.

How to Mitigate CVE-2026-78199

Immediate Actions Required

Restrict internet exposure of the Simple Online Food Ordering System until a fix is applied.
Place the application behind a WAF configured to block SQL injection payloads targeting the ID parameter.
Rotate database credentials and audit accounts that hold write access to the application schema.

Patch Information

No official vendor patch has been referenced in the NVD entry at time of publication. Administrators should modify the vulnerable code path to use prepared statements with bound parameters and enforce strict type validation on the ID argument. Refer to the VulDB advisory for CVE-2026-78199 and the SourceCodester project site for updates.

Workarounds

Cast the ID parameter to an integer server-side before it reaches any SQL query.
Apply WAF rules that reject non-numeric characters in the ID argument for /fos/view_prod.php.
Restrict the database account used by the application to SELECT on only the tables required by the storefront.

bash

# Example nginx rule to enforce numeric-only ID values
location = /fos/view_prod.php {
    if ($arg_id !~ "^[0-9]+$") {
        return 403;
    }
    include fastcgi_params;
    fastcgi_pass unix:/run/php/php-fpm.sock;
}
