Vulnerability Data
OpenSearch is a community-driven, open source fork of Elasticsearch and Kibana following the license change in early 2021. There is an issue with the implementation of tenant permissions in OpenSearch Dashboards where authenticated users with read-only access to a tenant…

can perform create, edit and delete operations on index metadata of dashboards and visualizations in that tenant, potentially rendering them unavailable. This issue does not affect index data, only metadata. Dashboards correctly enforces read-only permissions when indexing and updating documents. This issue does not provide additional read access to data users don’t already have. This issue can be mitigated by disabling the tenants functionality for the cluster. Versions 1.3.14 and 2.11.0 contain a fix for this issue.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Forces removal or modification of permissions no longer required after reassignment, preventing improper preservation of old access rights.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege permission policies and reviews directly prevents incorrect permission propagation on copy/restore/share operations.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Access-control policy defines how permissions must be preserved when objects are copied or shared.
Access-rights provisioning and review processes directly address the risk of overly permissive copied objects.
Privileged-access management includes rules for maintaining correct permissions on copied or restored data.
Information-access-restriction controls enforce least-privilege permissions that must be preserved during copy/restore operations.
Change-management procedures can require verification that permissions remain intact after modifications or restores.
Configuration baselines can embed permission settings, indirectly reducing the chance of incorrect preservation.
