Summary
CVE-2026-102458 is a missing authentication vulnerability (CWE-306) in Digiwin’s EasyFlow .NET workflow automation platform. An unauthenticated remote attacker can query a specific API endpoint to retrieve other users’ passwords in plaintext, fully compromising account confidentiality. The flaw carries a Critical severity rating (CVSS 9.3–9.8 depending on scoring version).
Technical details
- Root cause: A specific API in EasyFlow .NET fails to enforce authentication/authorization checks before returning user credential data.
- Trigger conditions: No authentication or user interaction is required; the attacker only needs network access to the exposed API endpoint.
- Attack vector: Network — the vulnerable API is reachable over HTTP(S) without any prior session or credentials.
- Impact: Disclosure of other users’ plaintext passwords, enabling account takeover and further lateral movement within the affected environment.
Affected software
- Digiwin EasyFlow .NET V6.1.x and earlier
- Digiwin EasyFlow .NET V6.6 through V6.6.19
- Digiwin EasyFlow .NET V8.1 through V8.1.5
Severity
- CVSS v3.1 Base Score: 9.8 (Critical) — Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H - CVSS v4.0 Base Score: 9.3 (Critical) — Vector:
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Mitigation and recommended actions
- Immediate: Upgrade to the Digiwin EasyFlow .NET version released after April 17, 2026, which contains the fix for this issue.
- If patching is not immediately possible: Restrict network access to the EasyFlow .NET application to trusted internal networks only, and monitor for anomalous requests to authentication-related APIs. Force a password reset for all users once the patch has been applied, as previously exposed credentials should be considered compromised.
