Deeper analysisAI
CVE-2026-3754 is a SQL injection vulnerability in SourceCodester Sales and Inventory System 1.0, affecting an unknown function in the file /add_stock.php. The issue arises from improper neutralization of the 'cost' argument, classified under CWE-74 and CWE-89. 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), indicating medium severity with network accessibility, low attack complexity, and requirements for low privileges.
Attackers with low-privileged remote access, such as authenticated users, can exploit this vulnerability by manipulating the 'cost' parameter in requests to /add_stock.php, leading to SQL injection. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, potentially allowing unauthorized data access, modification, or disruption within the application's database.
Advisories from VulDB (ctiid.349732, id.349732, submit.768038) document the vulnerability and reference a public proof-of-concept exploit available on GitHub at meifukun/Web-Security-PoCs/blob/main/Inventory-System/SQLi-AddStock-cost.md. The vendor site at sourcecodester.com provides the affected software but no specific patch details are noted in available references; practitioners should verify for updates and apply input validation or parameterized queries as general mitigations.
The exploit has been publicly disclosed and could be used against unpatched instances of the system.
