Deeper analysis
CVE-2026-3756 is a SQL injection vulnerability (CWE-74, CWE-89) in the SourceCodester Sales and Inventory System up to version 1.0. The flaw affects an unknown function in the file /check_item_details.php, where manipulation of the stock_name1 argument enables SQL injection. Published on 2026-03-08T18:15:49.753, it carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
A remote attacker with low privileges can exploit this vulnerability over the network with low attack complexity and no user interaction. Exploitation involves injecting malicious SQL via the stock_name1 parameter, potentially allowing limited unauthorized access to data (confidentiality), modification of data (integrity), or disruption of services (availability).
VulDB advisories (ctiid.349734, id.349734, submit.768042) document the issue, and a proof-of-concept exploit is publicly available on GitHub. The vendor site at www.sourcecodester.com provides the affected software, but no patches or specific mitigations are detailed in the references.
The public availability of the exploit suggests potential for real-world use against unpatched instances.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of the stock_name1 input parameter to reject malformed SQL syntax before it reaches the database in check_item_details.php.
Boundary protection devices such as WAFs can inspect and block the malicious SQL payloads sent remotely to the vulnerable PHP endpoint.
System monitoring can identify anomalous SQL statements or error patterns originating from the stock_name1 parameter during exploitation attempts.
