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
Control ID IDSecure 4.7.26.0 and prior uses a hardcoded cryptographic key in order to sign and verify JWT session tokens, allowing attackers to sign arbitrary session tokens and bypass authentication.

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

Control ID IDSecure versions 4.7.26.0 and prior contain a hardcoded cryptographic key embedded in the application code. This key is used to sign and verify JWT session tokens. Because the key is static and discoverable (through code review, binary analysis, or other means), an attacker who obtains the key can forge valid JWT tokens with arbitrary claims, effectively impersonating any user and bypassing authentication entirely.

MitigationReplace the hardcoded cryptographic key with a secure, dynamically-managed key (e.g., environment variable, secure key vault, or hardware security module). Invalidate all existing sessions and require re-authentication after the fix. Consider upgrading to a version beyond 4.7.26.0 if the vendor has released a patched release.

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 IDSecure installation and version
    Locate the IDSecure application on the system and determine its installed version. This may be found in the application directory, program files, or through system inventory tools. Check the application's 'About' or version information panel if accessible.
    Affected if The installed version is 4.7.26.0 or any version prior to it.
  2. Locate application binaries or source code
    Find the IDSecure application binaries, DLLs, or any accessible source code files. Common locations include installation directories under Program Files or application data folders. Use file search tools to identify executable files associated with IDSecure.
    Affected if The application binaries or code exist on the system, indicating IDSecure is present.
  3. Search for hardcoded cryptographic key in binaries
    Perform binary analysis or string search on the IDSecure executable files and DLLs. Look for static strings that resemble cryptographic keys (typically long alphanumeric strings, Base64-encoded values, or hex sequences). Use tools like 'strings' on Linux or similar binary analysis tools on Windows. Pay particular attention to files handling authentication or session management.
    Affected if A static, hardcoded key string is found embedded in the application binaries, especially in files related to JWT token handling or authentication.
  4. Inspect JWT token validation implementation
    If accessible, examine the application configuration or code responsible for JWT token signing and verification. Look for any references to a static key value that is compiled or embedded rather than loaded from an external secure source.
    Affected if The JWT implementation uses a hardcoded key value instead of retrieving it from an environment variable, secure vault, or HSM.

The environment is affected if IDSecure version 4.7.26.0 or prior is installed and a static cryptographic key is found embedded in the application binaries or code used for JWT token signing.

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.

From vendor data
Upgrade available Upgrade to a release after 4.7.26.0
Interim mitigation

Replace the hardcoded cryptographic key with a secure, dynamically-managed key (e.g., environment variable, secure key vault, or hardware security module). Invalidate all existing sessions and require re-authentication after the fix. Consider upgrading to a version beyond 4.7.26.0 if the vendor has released a patched release.
