CVE-2026-4396
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper certificate validation in Devolutions Hub Reporting Service 2025.3.1.1 and earlier allows a network attacker to perform a man-in-the-middle attack via disabled TLS certificate verification.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDevolutions Hub Reporting Service versions 2025.3.1.1 and earlier have TLS certificate verification disabled, allowing attackers on the same network to intercept communications via man-in-the-middle attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Devolutions Hub Reporting Service versionLocate and inspect the installed Devolutions Hub Reporting Service version using the service's built-in version command, about dialog, or installation directory metadataAffected if the installed version is 2025.3.1.1 or earlier, or any version below 2026.1.1.0
-
Locate the service configuration fileFind the configuration file for Devolutions Hub Reporting Service - typically located in the installation folder or service data directory where runtime settings are storedAffected if the configuration file exists and contains TLS-related settings
-
Check TLS certificate verification settingOpen the configuration file and search for TLS, SSL, certificate verification, or secure communication settings. Verify whether certificate verification is explicitly disabled or set to a disabled/insecure stateAffected if certificate verification is set to disabled, false, no, or a similar insecure value, or is missing when it should be present
-
Verify client-server communication modeInspect the service configuration or documentation to confirm whether client-server communications are configured to use TLS/SSLAffected if TLS is enabled but certificate verification is disabled, creating the vulnerable MITM condition
You are affected if Devolutions Hub Reporting Service is installed at a version below 2026.1.1.0 AND TLS certificate verification is disabled in the service configuration, allowing unprotected network traffic.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2026.1.1.0
Enable TLS certificate validation in the service configuration or upgrade to a version where certificate verification is properly implemented.
2026.1.1.0
- Identify the current version of Devolutions Hub Reporting Service installed
- Download Devolutions Hub Reporting Service version 2026.1.1.0 or later from the official Devolutions website
- Stop the Hub Reporting Service before upgrading
- Install the updated version (2026.1.1.0 or newer) following the standard installation procedure
- Restart the Hub Reporting Service after installation
- Verify that TLS certificate verification is now properly enabled and the service is functioning correctly
