CVE-2026-79845: Simple Inventory System 1.0 SQLi Vulnerability

CVE-2026-79845 Overview

CVE-2026-79845 is a SQL injection vulnerability in code-projects Simple Inventory System 1.0. The flaw resides in /InventoryManagement/edit.php, where the ID parameter is passed to a database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements against the backend database. The vulnerability is exploitable remotely over the network and requires no authentication or user interaction. Public exploit details have been disclosed through a GitHub SQL Injection Advisory and are tracked in the VulDB CVE-2026-79845 entry.

Critical Impact
Unauthenticated remote attackers can inject SQL statements through the ID parameter of edit.php, exposing inventory data and potentially altering database records.

Affected Products

code-projects Simple Inventory System 1.0
The vulnerable component is /InventoryManagement/edit.php
The affected input is the ID request parameter

Technical Details for CVE-2026-79845

Vulnerability Analysis

The vulnerability is a SQL injection flaw categorized under [CWE-74] Improper Neutralization of Special Elements in Output Used by a Downstream Component. It affects the edit.php script within the Simple Inventory System application. The ID parameter reaches the SQL query without validation or parameterization. Attackers can append additional SQL clauses to alter query logic. Successful exploitation can expose inventory records, modify entries, or reveal database schema information. Because the application is a small PHP project intended for learning environments, exposed deployments are the primary risk surface.

Root Cause

The root cause is direct concatenation of the untrusted ID value into a SQL statement inside /InventoryManagement/edit.php. The application does not use prepared statements or bind parameters. It also does not enforce type constraints on the incoming value. Any character permitted by the HTTP layer flows through to the query executor.

Attack Vector

An attacker sends a crafted HTTP request to /InventoryManagement/edit.php with a manipulated ID parameter. No credentials or session state are required. The injected payload alters the query executed by the MySQL backend. Depending on backend privileges, the attacker can read arbitrary tables or write to inventory records. Details of the payload structure are documented in the GitHub SQL Injection Advisory.

No verified proof-of-concept code is reproduced here. Refer to the linked advisory for the exact request format used in public demonstrations.

Detection Methods for CVE-2026-79845

Indicators of Compromise

Requests to /InventoryManagement/edit.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or sleep( in the ID parameter.
Unexpected database errors logged by the PHP application or the MySQL server tied to the edit.php endpoint.
Anomalous outbound data volumes from the web server following requests to edit.php.

Detection Strategies

Deploy web application firewall rules that flag SQL syntax in the ID parameter of edit.php.
Enable MySQL general query logging temporarily to identify malformed or injected statements originating from the inventory application.
Correlate web access logs with database error logs to surface repeated failed queries from a single source address.

Monitoring Recommendations

Alert on HTTP 500 responses from /InventoryManagement/edit.php combined with unusual ID parameter length.
Track requests to edit.php from source addresses that have not previously authenticated to the application.
Monitor MySQL for INFORMATION_SCHEMA queries originating from the inventory database account.

How to Mitigate CVE-2026-79845

Immediate Actions Required

Restrict network access to the Simple Inventory System deployment to trusted internal networks only.
Place the application behind a web application firewall with SQL injection signatures enabled.
Revoke unnecessary privileges from the MySQL account used by the inventory application.
Review web and database logs for prior exploitation attempts targeting edit.php.

Patch Information

No vendor patch has been published for code-projects Simple Inventory System 1.0 at the time of NVD publication. Consult the Code Projects Resource Hub and the VulDB Vulnerability #395058 entry for updates. Organizations running this application should treat it as unmaintained software and plan migration to a supported inventory platform.

Workarounds

Modify /InventoryManagement/edit.php locally to use PHP Data Objects (PDO) prepared statements with bound parameters for the ID value.
Cast the ID value to an integer with intval() before it is used in any SQL query.
Remove or disable the edit.php endpoint if the edit workflow is not required in the current deployment.
Isolate the application in a container or virtual machine with no access to production data.

bash

# Example nginx location block restricting access to edit.php
location /InventoryManagement/edit.php {
    allow 10.0.0.0/8;
    deny all;
}
