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

Deeper analysis

CVE-2026-5645 is a SQL injection vulnerability (CWE-74, CWE-89) affecting projectworlds Car Rental System 1.0. The flaw resides in an unknown functionality of the file /pay.php within the Parameter Handler component, where manipulation of the 'mpesa' argument enables injection of malicious SQL code. Published on 2026-04-06, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and low complexity.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted requests to the vulnerable endpoint. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, such as extracting sensitive data, modifying database contents, or disrupting service. An exploit has been made publicly available, increasing the risk of real-world attacks.

Advisories and details are documented in references including a GitHub issue at https://github.com/2840364044/SQL-Vulnerability-database/issues/1 and VulDB entries at https://vuldb.com/submit/786149, https://vuldb.com/vuln/355433, and https://vuldb.com/vuln/355433/cti.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly prevents SQL injection by enforcing validation of the untrusted 'mpesa' parameter in /pay.php before database queries.

SI-2 Flaw Remediation good match
prevent

Requires identification and remediation of the specific SQL injection flaw in the Car Rental System's Parameter Handler.

SC-7 Boundary Protection partial match
prevent

Boundary protection mechanisms inspect and filter inbound requests to block SQL injection attempts targeting /pay.php.
