CVE-2026-25894
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 · uneditedFUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An insecure default configuration in FUXA allows an unauthenticated, remote attacker to gain administrative access and execute arbitrary code on the server. This affects FUXA through version 1.2.9 when authentication is enabled, but the administrator JWT secret is not configured. This issue has been patched in FUXA version 1.2.10.
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 confidenceFUXA versions through 1.2.9 contain an insecure default configuration where authentication can be enabled without a configured administrator JWT secret. When this misconfiguration exists, unauthenticated remote attackers can obtain administrative access by bypassing JWT validation, leading to arbitrary code execution on the server.

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 installed FUXA versionLocate the version number in the FUXA installation - typically found in package.json file in the application root directory, or by accessing the /api/version endpoint if availableAffected if version is earlier than 1.2.10
-
Check if authentication is enabledReview the FUXA server configuration file (commonly settings.json or similar) for the 'authentication' or 'auth' settingAffected if authentication setting is set to true or enabled
-
Verify JWT secret configurationExamine the configuration file for the administrator JWT secret parameter - look for fields like 'jwtSecret', 'adminSecret', or similar authentication-related secret configurationsAffected if the JWT secret field is absent, empty, set to a default value, or contains a weak/placeholder secret string
-
Confirm authentication bypass exposureTest whether unauthenticated API endpoints that should require admin privileges are accessible - specifically check if administrative API routes accept requests without a valid JWT tokenAffected if administrative functions are accessible without valid authentication tokens or with manipulated/empty tokens
-
Review server startup logsCheck FUXA server startup logs for warnings about missing or weak JWT secret configuration during initializationAffected if logs indicate authentication is enabled but no proper JWT secret was configured
A FUXA installation is affected if it runs version earlier than 1.2.10 with authentication enabled and either lacks a configured administrator JWT secret or uses a default/weak secret, allowing potential administrative access bypass.

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 · scoped1.2.10
Upgrade to FUXA version 1.2.10 or later and ensure a strong administrator JWT secret is properly configured when authentication is enabled.
1.2.10
- Upgrade FUXA to version 1.2.10 or later using your deployment method (npm, Docker, or binary)
- After upgrading, verify that a strong JWT secret is configured in your settings.json or environment variables (setting 'jwtSecret' under the 'server' configuration section)
