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
Kiteworks is a private data network (PDN). Prior to version 9.2.1, a vulnerability in Kiteworks Email Protection Gateway session management allows blocked users to maintain active sessions after their account is disabled. This could allow unauthorized access to continue until the session naturally expires. Upgrade Kiteworks to version 9.2.1 or later to receive a patch.

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

This is a session management vulnerability in the Kiteworks Email Protection Gateway where disabled/blocked users retain active sessions after account disablement. Sessions remain valid until natural expiration rather than being invalidated immediately, allowing unauthorized access to continue.

MitigationUpgrade Kiteworks to version 9.2.1 or later to receive the patch that properly invalidates sessions upon account disablement.

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. Verify Kiteworks version
    Retrieve the currently installed Kiteworks version from the system or admin interface and compare it to the affected range of versions prior to 9.2.1
    Affected if The installed version is below 9.2.1
  2. Confirm Email Protection Gateway is enabled
    Determine whether the Email Protection Gateway module is configured and active in the Kiteworks deployment
    Affected if Email Protection Gateway is enabled and the version is below 9.2.1
  3. Inspect active sessions for disabled accounts
    Use admin tools or session management interfaces to list active user sessions, then cross-reference against the list of disabled or blocked user accounts
    Affected if Active sessions exist for users whose accounts have been disabled or blocked and the version is below 9.2.1

The environment is affected if running Kiteworks version below 9.2.1 with Email Protection Gateway enabled and active sessions are found for disabled user accounts.
