Deeper analysis
CVE-2026-4570 is a SQL injection vulnerability in the SourceCodester Sales and Inventory System 1.0. The flaw affects an unknown function within the file /view_customers.php, specifically in the HTTP POST Request Handler component. By manipulating the 'searchtxt' argument, attackers can inject malicious SQL payloads, as classified under CWE-74 (Improper Neutralization of Special Elements) and CWE-89 (SQL Injection). The vulnerability 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) and was published on 2026-03-23.
The vulnerability can be exploited remotely by an attacker with low privileges (PR:L), requiring network access but low complexity and no user interaction. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption within the affected system's database.
Advisories from VulDB (ctiid.352407, id.352407, submit.775165) document the issue and reference a public proof-of-concept exploit available on GitHub at https://github.com/meifukun/Web-Security-PoCs/blob/main/Inventory-System/SQLi-ViewCustomers-searchtxt.md. No patches or specific mitigations are detailed in the provided references, though the vendor site at https://www.sourcecodester.com/ hosts the affected software.
The exploit is publicly available and might be used in real-world attacks, increasing the risk for unpatched instances of the system.
