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 · unedited
European Chemicals Agency IUCLID 6.x before 6.27.6 allows authentication bypass because a weak hard-coded secret is used for JWT signing. The affected versions are 5.15.0 through 6.27.5.

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 confidence

IUCLID 6.x versions 5.15.0 through 6.27.5 use a weak hard-coded secret for JWT token signing, allowing attackers to forge authentication tokens and bypass the authentication mechanism entirely.

MitigationUpgrade IUCLID to version 6.27.6 or later which replaces the hard-coded secret with proper secret management. If immediate patching is not feasible, restrict network access to the application and implement additional authentication controls.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify IUCLID installed version
    Locate the IUCLID version number in the application UI (typically under Help > About or in the login page footer) or check the installation directory for a version file. If deployed as a server, check the startup logs or administrative interface for the version string.
    Affected if The displayed version falls within the range >= 5.15.0 and < 6.27.6 (versions 5.15.0 through 6.27.5)
  2. Confirm version matches vulnerable range
    Compare the identified version number against the affected range. Note that versions 5.15.0 through 6.27.5 inclusive are affected. Versions below 5.15.0 or at/above 6.27.6 are not vulnerable.
    Affected if The installed version is 5.15.0, 5.16.0, 5.17.0, 5.18.0, 5.19.0, 5.20.0, 5.21.0, 5.22.0, 5.23.0, 5.24.0, 5.25.0, 5.26.0, 5.27.0, 6.0.0 through 6.27.5, or any version in between these ranges

If the IUCLID version is 6.27.5 or earlier but 5.15.0 or later, the hard-coded JWT signing secret vulnerability is present and authentication can be bypassed.

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 · scoped
Upgrade available Upgrade to 6.27.6 or later
Fixed in 6.27.6
Interim mitigation

Upgrade IUCLID to version 6.27.6 or later which replaces the hard-coded secret with proper secret management. If immediate patching is not feasible, restrict network access to the application and implement additional authentication controls.

Recommended fix High confidence

6.27.6

  1. Contact your system administrator or ECHA support to obtain the upgrade package for version 6.27.6
  2. Follow the standard IUCLID upgrade procedure in your environment (typically involves backing up the current installation and database, stopping the service, replacing files, and restarting)
  3. After upgrade, verify the JWT authentication is functioning correctly with the new secret
