EasyFlow .NET API Plaintext Password Exposure

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-102458

The vulnerability resides in an API endpoint within the EasyFlow .NET application. Such applications are commonly deployed as web-based enterprise workflow systems that are often exposed to the network to facilitate remote access for users, making the API surface plausibly reachable in common deployments.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability affects EasyFlow .NET applications, which could allow unauthenticated attackers to access plaintext passwords through a specific API. The primary concern is to confirm if this technology is in use and assess any potential exposure.

  • Unauthenticated access to user passwords.
  • Potential for widespread credential compromise.
  • Confirm relevance and assess exposure.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by interacting with a specific API in the EasyFlow .NET application. No authentication is required, meaning an unauthenticated remote attacker can potentially access sensitive information, such as other users' plaintext passwords.

  • No authentication required.
  • Specific API endpoint trigger.
  • Exposure of user passwords.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, an unauthenticated remote attacker could exploit a missing authentication vulnerability in a specific API of EasyFlow .NET. This could allow them to retrieve other users' passwords in plaintext.

  • Other users' plaintext passwords.
  • Via a specific API endpoint.
  • Unauthorized access to user accounts.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability in EasyFlow .NET, which exposes plaintext passwords via an API, likely impacts application owners and platform teams responsible for the Digiwin EasyFlow .NET deployment. The first practical step is to identify all instances of EasyFlow .NET, determine their reachability and criticality, and assign an owner for remediation planning.

  • Identify EasyFlow .NET instances and criticality.
  • Confirm application owner and vendor contact.
  • Plan risk-based remediation and vendor coordination.

Frequently asked questions

What is EasyFlow .NET by Digiwin?

EasyFlow .NET is a web-based enterprise workflow management system developed by Digiwin. Organizations use this software to automate business processes, route documents, and manage digital approvals across their internal teams. Because it handles sensitive organizational workflows, it typically stores user accounts and authentication data within its infrastructure.

What does the Missing Authentication weakness mean for CVE-2026-102458?

This vulnerability, classified as CWE-306, means the application fails to verify who is requesting information before providing it. Specifically, in this CVE, the system's security controls are bypassed, allowing an unauthenticated remote party to interact with a specific API endpoint that should only be accessible to authorized users.

How is this API vulnerability triggered?

An attacker triggers this bug by sending requests directly to the affected API endpoint within the EasyFlow .NET software. Because the system lacks proper authentication checks, it will respond to these requests by revealing plaintext passwords. It is important to note that performing legitimate administrative or user tasks within the application is not required to trigger this vulnerability.

Is my EasyFlow .NET instance at risk?

According to Halo Surface Signal, this vulnerability is particularly relevant if your EasyFlow .NET instance is network-accessible. Because these applications are often deployed to support remote work and external workflow participation, they are frequently placed on segments reachable from the network, increasing the likelihood that an attacker could reach the vulnerable API.

Do I need to take action if I use this software?

Yes. Your first priority is to create an inventory of all EasyFlow .NET deployments to understand where the software is running. Once identified, evaluate the network accessibility of these instances to determine which are most exposed. Finally, contact Digiwin to inquire about available updates or guidance, and establish an owner to manage the remediation process.
