CVE-2026-9411
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in SourceCodester Indian Invoicing System 1.0. This issue affects some unknown processing of the file /Invoicing/IGST_Invoice.php of the component Invoice Generation Handler. Performing a manipulation of the argument customer_name/category results in sql injection. The attack can be initiated remotely. The exploit has been made public and could be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSQL injection vulnerability in SourceCodester Indian Invoicing System 1.0 allows remote attackers to manipulate the customer_name or category parameters in /Invoicing/IGST_Invoice.php to inject arbitrary SQL queries. The Invoice Generation Handler lacks proper input sanitization or parameterized queries, enabling database compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the IGST_Invoice.php fileSearch the web server document root for the file at path /Invoicing/IGST_Invoice.php or similar path patterns like /Invoicing/ and IGST_Invoice.phpAffected if The file exists in the application directory structure, indicating the Indian Invoicing System is deployed
-
Confirm the application versionCheck for a version indicator in the application source code, such as a version.php file, README, or version string in the main includes/config file. Compare against version 1.0Affected if The installed version matches 1.0 of SourceCodester Indian Invoicing System
-
Inspect the invoice generation functionalityExamine the IGST_Invoice.php file source code and look for SQL query handling that includes the customer_name and category parameters without prepared statement usageAffected if The code directly incorporates customer_name and category parameters into SQL queries without parameterized binding
-
Verify parameter exposure in the applicationTest accessing the invoice generation page (typically accessed via browser at the /Invoicing/IGST_Invoice.php endpoint) and verify the customer_name and category input fields are present and functionalAffected if The application serves the invoice generation page with user-controllable customer_name and category input fields
-
Check database user privilegesReview the database configuration file (commonly config.php or db.php in the application root or includes folder) to identify the database user account credentials used by the applicationAffected if The database user has privileges beyond read-only access, allowing the injected SQL to potentially modify or extract data
The environment is affected if SourceCodester Indian Invoicing System version 1.0 is deployed with the IGST_Invoice.php file accessible and the customer_name/category parameters are handled without prepared statements in SQL queries.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with prepared statements/parameterized queries in IGST_Invoice.php and apply input validation on all user-supplied parameters. If no vendor patch exists, consider deploying a WAF as an interim control.
