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
Multiple insufficient session expiration weaknesses [CWE-613] vulnerability in Fortinet FortiAIOps 2.0.0 may allow an attacker to re-use stolen old session tokens to perform unauthorized operations via crafted requests.

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

Fortinet FortiAIOps 2.0.0 contains a session expiration vulnerability where session tokens remain valid indefinitely after authentication. Attackers who obtain old or stolen session tokens can reuse them in crafted HTTP requests to perform unauthorized operations, bypassing the need for valid current credentials.

MitigationImplement proper session expiration by enforcing finite session lifetimes, invalidating sessions after logout or inactivity timeout, and ensuring old/stale session tokens are rejected at authentication.

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 FortiAIOps version
    Access the FortiAIOps admin interface or CLI and locate the system version information. Typically found under System > Settings > About or via CLI command 'get system status'.
    Affected if The installed version is exactly FortiAIOps 2.0.0
  2. Locate session management configuration
    Navigate to System > Administration > Session or User > Session Settings in the FortiAIOps web interface. Look for session-related configuration panels.
    Affected if Session management settings are accessible and visible in the interface
  3. Verify session timeout configuration
    Inspect the session timeout or expiration setting within the session management panel. Record the configured timeout duration if present.
    Affected if No session timeout is configured, or timeout is set to an excessively long duration or disabled entirely
  4. Check session expiration policy
    Review any available session policy settings that control how long sessions remain valid after authentication, including idle timeout and absolute session lifetime.
    Affected if Sessions are configured to never expire or there is no enforced maximum session lifetime
  5. Test session token validity period
    If possible, authenticate to FortiAIOps, obtain a session token, wait beyond a reasonable period, then attempt to use the original token in an API request. Alternatively, review session logs for token validation behavior.
    Affected if Old session tokens continue to be accepted and remain valid after extended periods or after user logout
  6. Review authentication settings
    Examine the authentication configuration for any settings related to token validation, session renewal, or automatic logout. Look for options controlling token reuse or session invalidation.
    Affected if Authentication settings allow indefinite session token reuse without re-validation

A user is affected if they are running FortiAIOps version 2.0.0 and sessions do not have enforced expiration or invalidation of old tokens.
