CVE-2024-39900 — OpenSearch Dashboards Reports allows ‘Report Owner’ export and share reports from OpenSearch Dashboards

Medium CVSS 5.4

OpenSearch Dashboards Reports allows ‘Report Owner’ export and share reports from OpenSearch Dashboards. An issue in the OpenSearch reporting plugin allows unintended access to private tenant resources like notebooks. The system did not properly check if the user was the resource author when accessing resources in a private tenant, leading to potential data being revealed. The patches are included in OpenSearch 2.14.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
