CVE-2026-3753
Published: 08 March 2026
Summary
CVE-2026-3753 is a medium-severity Injection (CWE-74) vulnerability in Ahsanriaz26Gmailcom Sales And Inventory System. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 21.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-3753 is a SQL injection vulnerability in SourceCodester Sales and Inventory System up to version 1.0. The flaw affects an unknown function in the file /add_sales_print.php, where manipulation of the 'sid' argument enables SQL injection. Published on 2026-03-08, it has 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 maps to CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection).
A remote attacker with low privileges, such as an authenticated user, can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows arbitrary SQL query execution via the 'sid' parameter, resulting in low-level impacts to confidentiality (e.g., limited data exposure), integrity (e.g., minor data modification), and availability (e.g., minor denial of service).
VulDB advisories (ctiid.349731, id.349731, submit.768037) document the issue, and a proof-of-concept exploit is publicly available on GitHub at meifukun/Web-Security-PoCs/blob/main/Inventory-System/SQLi-AddSalesPrint-sid.md, noting that it may be used. The vendor site at sourcecodester.com provides context on the affected software, though no specific patches are detailed in the referenced sources.
The exploit disclosure heightens risk for exposed instances, as the PoC enables ready replication by practitioners testing defenses.

Why these techniques?
SQL injection in a remotely accessible web app directly enables T1190 exploitation of the application for access; arbitrary SQL execution facilitates T1213.006 data collection from the backend database.

Directly requires validation and neutralization of untrusted input such as the 'sid' parameter before it reaches SQL statements in add_sales_print.php.
Limits the privileges of authenticated users so that even a successful SQL injection via 'sid' can only affect a narrow data scope.
Enables monitoring and alerting on anomalous database queries or error patterns that would result from exploitation of the disclosed PoC.
