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
OpenObserve is a cloud-native observability platform. Prior to version 0.16.0, organization invitation tokens do not expire once issued, remain valid even after the invited user is removed from the organization, and allow multiple invitations to the same email with different roles where all issued links remain valid simultaneously. This results in broken access control where a removed or demoted user can regain access or escalate privileges. This issue has been patched in version 0.16.0.

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

OpenObserve versions before 0.16.0 have broken access control in the organization invitation system where invitation tokens never expire, remain valid after the invited user is removed from the organization, and allow multiple simultaneous invitations to the same email with different roles. This enables removed or demoted users to regain access or escalate privileges by using old invitation links.

MitigationUpgrade to version 0.16.0 or later which implements token expiration and invalidation logic for organization invitations.

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 OpenObserve version
    Check the running OpenObserve instance version via the UI, API (e.g., GET /api/version), or container/container orchestration metadata. Compare the version number to the 0.16.0 threshold.
    Affected if The installed version is below 0.16.0 (e.g., 0.15.x, 0.14.x, etc.)
  2. Verify organization invitation feature is in use
    Query the database or API to list active organization invitations (e.g., GET /api/organizations/{org_id}/invitations or inspect the invitations table). Determine if any invitations exist.
    Affected if The organization invitation feature is actively used and there are pending or historical invitations in the system.
  3. Check for dangling invitations
    Review the invitation list to identify invitations for users who have since been removed from the organization. Cross-reference invitation records against current organization member list.
    Affected if Invitations exist for emails associated with users who are no longer members of the organization.
  4. Check for duplicate email invitations with different roles
    Query the invitation records to identify cases where the same email address appears multiple times with different role assignments.
    Affected if The same email address has multiple active invitations with different roles.

If OpenObserve version is below 0.16.0 AND the organization invitation system is in use with active or historical invitations, the environment is affected by this broken access control flaw.

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

Upgrade to version 0.16.0 or later which implements token expiration and invalidation logic for organization invitations.

Recommended fix High confidence

0.16.0

  1. Identify the current OpenObserve version in use (e.g., check deployment manifests, Docker tags, or running service version)
  2. Plan downtime or service restart as required by the deployment method
  3. Upgrade OpenObserve to version 0.16.0 or later
  4. Verify the upgrade was successful by checking the version number
  5. Test invitation functionality: create a new invitation, verify it expires as expected, and ensure previously issued invitations are invalidated or properly handled
