Summary

CVE-2026-37347 is a critical-severity SQL Injection (CWE-89) vulnerability. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 23.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-37347 is a SQL injection vulnerability (CWE-89) in SourceCodester Payroll Management and Information System version 1.0, specifically within the file /payroll/view_employee.php. Published on 2026-04-16, it carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), classifying it as critical due to its potential for high-impact data exposure and manipulation.

The vulnerability can be exploited by any unauthenticated attacker over the network with low attack complexity and no user interaction required. Successful exploitation grants high confidentiality and integrity impacts, allowing attackers to inject malicious SQL queries to extract sensitive payroll data, modify records, or potentially escalate to broader database compromise.

A detailed report on the vulnerability, including potential mitigation guidance, is available in the referenced advisory at https://github.com/mt-0505/cve-report/blob/main/sourcecodester/payroll-management-and-information-system/SQL-2.md.

T1213.006 Databases Collection
Adversaries may leverage databases to mine valuable information.
attack.mitre.org →
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.

Why these techniques?

SQL injection in public-facing web app directly enables T1190 for remote exploitation; facilitates database data collection (T1213.006) and stored data modification (T1565.001) via malicious queries.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly prevents SQL injection in /payroll/view_employee.php by requiring validation and sanitization of user inputs before database query construction.

SI-2 Flaw Remediation good match
prevent

Mandates timely identification, reporting, and correction of the specific SQL injection flaw documented in this CVE.

AC-6 Least Privilege partial match
prevent

Limits the impact of successful SQL injection exploitation by enforcing least privilege on the application's database account, reducing confidentiality and integrity damage to payroll data.
