  "title": "Authentication bypass through empty external passwords in OpenObserve",
  "summary": "OpenObserve before 1.1.0 can accept an empty or whitespace-only HTTP Basic password for accounts with a missing or empty external-password value. An unauthenticated attacker who knows an affected user's email address and organization may authenticate to protected non-ingestion API routes with that user's permissions. Affected accounts include certain SSO-provisioned and migrated users.",
  "mitigation": "Upgrade OpenObserve to version 1.1.0 or later. Until the upgrade is complete, restrict access to the affected API endpoints and review SSO-provisioned and migrated accounts for missing or empty external-password values.",
