CVE-2026-11495: Ingredients Stock Management SQLi Flaw

CVE-2026-11495 Overview

CVE-2026-11495 is a SQL injection vulnerability in CodeAstro Ingredients Stock Management System 1.0. The flaw resides in the /Ingredients-Stock/add_stock.php endpoint, where the ID parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The weakness is classified under CWE-74 (Improper Neutralization of Special Elements). A public exploit is referenced through VulDB CVE-2026-11495 and a corresponding GitHub issue, lowering the barrier to exploitation.

Critical Impact
Remote attackers with low-level privileges can inject SQL through the ID parameter of add_stock.php, potentially exposing or modifying stock records and underlying database content.

Affected Products

CodeAstro Ingredients Stock Management System 1.0
The vulnerable component is /Ingredients-Stock/add_stock.php

Technical Details for CVE-2026-11495

Vulnerability Analysis

The vulnerability is a SQL injection in the add_stock.php script of CodeAstro Ingredients Stock Management System 1.0. The application accepts an ID argument from an HTTP request and incorporates it directly into a SQL statement. Because the parameter is not sanitized, parameterized, or strongly typed, an attacker can append SQL syntax that alters the original query.

Exploitation requires network access to the application and a low-privileged authenticated session. No user interaction is needed. Successful injection allows reading, modifying, or deleting stock records, and depending on the database user's permissions, may expose additional tables in the same schema.

The attack surface is the web frontend, and exploitation can be automated using standard SQL injection tooling against the ID parameter. Public exploit details are available through VulDB and the associated GitHub issue.

Root Cause

The root cause is improper neutralization of user-supplied input. The ID parameter received by add_stock.php is concatenated into a SQL query string instead of being bound through a prepared statement. This pattern is the canonical trigger for CWE-74 class injections.

Attack Vector

An authenticated attacker issues a crafted HTTP request to /Ingredients-Stock/add_stock.php with a malicious value in the ID parameter. The injected SQL fragment is executed by the backend database, returning data or performing actions outside the application's intended logic. The vulnerability is reachable remotely over the network.

No verified exploit code is included here. Refer to the VulDB advisory and the public GitHub issue for technical proof-of-concept details.

Detection Methods for CVE-2026-11495

Indicators of Compromise

HTTP requests to /Ingredients-Stock/add_stock.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP in the ID parameter.
Database error messages or unusually long response times originating from add_stock.php.
Repeated requests to add_stock.php from a single source with incrementing or fuzzed ID values.

Detection Strategies

Inspect web server access logs for add_stock.php requests where the ID parameter contains non-numeric characters or URL-encoded SQL syntax.
Deploy web application firewall (WAF) signatures for SQL injection patterns targeting the ID query parameter.
Enable database query logging and alert on syntactically anomalous queries originating from the application's database user.

Monitoring Recommendations

Continuously baseline normal add_stock.php traffic and alert on spikes in error responses (HTTP 500) or query latency.
Monitor authenticated user sessions that issue an abnormal volume of requests to stock management endpoints.
Correlate WAF blocks and database errors in a centralized log platform to surface multi-stage injection attempts.

How to Mitigate CVE-2026-11495

Immediate Actions Required

Restrict network access to the Ingredients Stock Management System to trusted users and internal networks only.
Place the application behind a WAF with active SQL injection rules covering the ID parameter.
Audit application database accounts and enforce least privilege, removing rights to drop or alter tables where not required.
Rotate credentials and review stock data integrity if exploitation is suspected.

Patch Information

No vendor patch is referenced in the advisory at the time of publication. Operators should monitor CodeAstro for updates and review the VulDB entry for any subsequent fix references. Where a vendor fix is unavailable, source-level remediation requires replacing string concatenation in add_stock.php with parameterized queries or prepared statements.

Workarounds

Modify add_stock.php to validate that the ID parameter is a positive integer before use, rejecting any other input.
Refactor the SQL statement in add_stock.php to use prepared statements with bound parameters (for example, PDO or mysqli parameterized queries).
Disable or remove the affected endpoint until source-level remediation is applied if business operations allow.

bash

# Example PHP refactor pattern for add_stock.php
# Replace direct concatenation with a prepared statement:
#
#   $stmt = $pdo->prepare('SELECT * FROM stock WHERE id = :id');
#   $stmt->bindValue(':id', (int)$_REQUEST['ID'], PDO::PARAM_INT);
#   $stmt->execute();
