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
HCL AION version 2 is affected by a JWT Token Expiry Too Long vulnerability. This may increase the risk of token misuse, potentially resulting in unauthorized access if the token is compromised.

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 · moderate confidence

HCL AION version 2 uses JWT tokens with an excessively long expiry period, which extends the window during which a stolen or compromised token can be abused by attackers to gain unauthorized access to the system.

MitigationReduce the JWT token expiry time to a reasonable duration (e.g., 15-60 minutes for access tokens) and implement refresh token rotation or short-lived token mechanisms.

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 HCL AION version
    Check the installed HCL AION version in your environment (typically via product documentation, installation directory, or version lookup command provided by HCL). Compare against version 2.0.0.
    Affected if The installed version is exactly 2.0.0
  2. Locate JWT configuration
    Identify where JWT token configuration is stored in your HCL AION 2.0.0 deployment. This may be in configuration files, a management console, or environment settings related to authentication.
    Affected if JWT token configuration is accessible and present in the environment
  3. Check JWT token expiry setting
    Inspect the JWT token expiry configuration value. Look for the 'expiration', 'expiresIn', 'tokenLifetime', or similar field that defines how long access tokens remain valid.
    Affected if The token expiry period is set to an excessive duration (significantly longer than typical best practice of 15-60 minutes)
  4. Verify token is in use
    Confirm that JWT-based authentication is actively enabled and used for API or system access in your HCL AION deployment.
    Affected if JWT authentication is enabled and tokens are being issued to users or services

You are affected if running HCL AION 2.0.0 with JWT token expiry configured to an excessive duration beyond reasonable security limits (typically hours or days rather than minutes).

Generated from the published advisory. Verify against your own configuration.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Reduce the JWT token expiry time to a reasonable duration (e.g., 15-60 minutes for access tokens) and implement refresh token rotation or short-lived token mechanisms.
