Deeper analysis
CVE-2026-3790 is a SQL injection vulnerability (CWE-74, CWE-89) in SourceCodester Sales and Inventory System 1.0, published on 2026-03-09. The flaw resides in an unknown functionality of the file check_supplier_details.php within the POST Parameter Handler component, where manipulation of the stock_name1 argument triggers the injection.
The vulnerability enables remote exploitation over the network with low complexity and low privileges required (PR:L), without user interaction (CVSS:3.1 score of 6.3; AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). Attackers can achieve limited impacts on confidentiality, integrity, and availability through SQL injection.
VulDB advisories (ctiid.349757, id.349757, submit.768045) document the issue, and a proof-of-concept exploit is available on GitHub at https://github.com/meifukun/Web-Security-PoCs/blob/main/Inventory-System/SQLi-CheckSupplierDetails-stockname1.md. The vendor site is at https://www.sourcecodester.com/, but no patches or mitigations are specified in the references.
The exploit has been published and may be used, heightening risks for exposed instances of the affected system.

Why these techniques?
Direct remote SQL injection in a web application (check_supplier_details.php POST handler) enables exploitation of a public-facing app per T1190; limited DB impacts do not map to additional techniques like command execution or credential dumping.

Directly requires validation and sanitization of untrusted POST parameters such as stock_name1 to block SQL injection payloads before they reach the database.
Limits the privileges of the database account used by check_supplier_details.php so that a successful injection yields only minimal confidentiality/integrity/availability impact.
Enables monitoring of application and database query logs to identify anomalous SQL statements originating from the vulnerable endpoint.
