Summary

CVE-2026-5964 is a critical-severity SQL Injection (CWE-89) vulnerability in Digiwin Easyflow .Net. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.3th 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).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly prevents SQL injection attacks in EasyFlow .NET by validating all user-supplied inputs before they are used in database queries.

SI-2 Flaw Remediation good match

prevent

Requires timely patching and remediation of the specific SQL injection vulnerability (CVE-2026-5964) in EasyFlow .NET.

SC-7 Boundary Protection partial match

prevent

Boundary protection with web application firewalls can inspect and block malicious SQL injection payloads targeting the unauthenticated endpoint.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1213.006 Databases Collection

Adversaries may leverage databases to mine valuable information.

Why these techniques?

SQL injection in public-facing application enables T1190 (Exploit Public-Facing Application) for unauthenticated remote exploitation and directly facilitates T1213.006 (Data from Information Repositories: Databases) via arbitrary SQL read access.
