CVE-2026-87925: Rizwan17 Inventory Management SQL Injection

CVE-2026-87925 Overview

CVE-2026-87925 is a SQL injection vulnerability in the Rizwan17 inventory-management-system project. The flaw resides in the storeCustomerOrderInvoice function within includes/manage.php. Attackers can manipulate the pro_name[] argument to inject SQL statements into the underlying query. The attack requires no authentication and can be initiated remotely across the network. Public exploit details have been disclosed, increasing exposure risk for deployed instances. Because the project uses continuous delivery with rolling releases, no discrete affected or fixed version identifiers exist. The maintainer received an early issue report but has not responded at the time of publication.

Critical Impact
Unauthenticated remote attackers can inject SQL through the pro_name[] parameter to read, modify, or corrupt inventory and customer order data.

Technical Details for CVE-2026-87925

Vulnerability Analysis

The vulnerability is a SQL injection classified under [CWE-74] Improper Neutralization of Special Elements in Output Used by a Downstream Component. The affected code path is storeCustomerOrderInvoice in includes/manage.php, which processes customer order invoice submissions. User-controlled values passed through the pro_name[] array parameter reach a database query without proper sanitization or parameterization. Because the parameter is an array, each element is concatenated into the SQL statement, giving attackers multiple injection points within a single request.

Successful exploitation allows an attacker to alter the query logic, extract arbitrary database records, or modify inventory and order data. The attack is remote and requires no authentication or user interaction.

Root Cause

The root cause is unsafe handling of the pro_name[] request parameter inside storeCustomerOrderInvoice. Values from the array are interpolated into the SQL statement instead of being bound as prepared-statement parameters. No input validation, type enforcement, or escaping is applied before query construction.

Attack Vector

An unauthenticated attacker sends a crafted HTTP request to the endpoint that invokes storeCustomerOrderInvoice. By supplying malicious payloads in one or more pro_name[] array elements, the attacker changes the semantics of the executed SQL statement. Because exploit information is public, opportunistic scanning and automated abuse are realistic risks.

See the VulDB entry for CVE-2026-87925 and the upstream GitHub issue #13 for reference details. No verified proof-of-concept code is reproduced here.

Detection Methods for CVE-2026-87925

Indicators of Compromise

HTTP POST requests to endpoints invoking storeCustomerOrderInvoice containing SQL metacharacters such as single quotes, UNION, SELECT, or comment sequences within pro_name[] values.
Web server or PHP error logs showing SQL syntax errors originating from includes/manage.php.
Unexpected database records, missing rows, or altered order and inventory tables tied to invoice submissions.

Detection Strategies

Deploy web application firewall rules that inspect pro_name[] array parameters for SQL injection patterns.
Enable database query logging and alert on syntax errors or anomalous query structures originating from the application user.
Correlate application logs with database logs to identify request-to-query paths that include untrusted string concatenation.

Monitoring Recommendations

Monitor outbound traffic from the database host for signs of data exfiltration following suspicious invoice submissions.
Track authentication-free endpoints for spikes in request volume or unusual user-agent strings.
Retain HTTP request bodies for endpoints that call storeCustomerOrderInvoice to support forensic analysis.

How to Mitigate CVE-2026-87925

Immediate Actions Required

Restrict network exposure of the inventory-management-system application to trusted networks until a fix is applied.
Deploy WAF signatures blocking SQL injection payloads in pro_name[] parameters submitted to includes/manage.php.
Audit recent invoice submissions and database logs for evidence of exploitation given that exploit details are public.

Patch Information

At the time of publication, the upstream maintainer has not released a patch. The project uses continuous delivery with rolling releases, so no fixed version identifier is available. Operators should track the upstream repository and GitHub issue #13 for remediation updates.

Workarounds

Modify storeCustomerOrderInvoice locally to use parameterized queries or prepared statements for every element of pro_name[].
Add server-side input validation that rejects non-alphanumeric characters in product name fields where feasible.
Place the application behind an authenticating reverse proxy to prevent unauthenticated access to invoice endpoints.
