Doc Text:	A flaw was found in Grafana's Elasticsearch data source. An authenticated user with permission to query the data source, such as a viewer, can send arbitrary requests to the connected Elasticsearch cluster using the data source's stored credentials. This allows an attacker to bypass intended restrictions, access data across unauthorized indices, and execute write operations to modify index configurations or data.	Story Points:	---

CVE-2026-106475: ELASTICSEARCH DATA SOURCE COULD BE USED TO SEND ARBITRARY REQUESTS TO ELASTICSEARCH

Score: 7.1 (HIGH) 

Short description of the vulnerability: 

A signed-in user who could query an Elasticsearch data source, including a Viewer, could send any request to the connected Elasticsearch cluster through the data source, using the data source's credentials. This included write operations, such as changing an index's field mappings, and requests to indices other than the one the data source is configured for. The fixed versions restrict which requests the data source can send. 

Known mitigations: 

Give the data source's Elasticsearch credentials a read-only role on the intended indices only, with no write or index management privileges. 

Affected products and versions: 

Grafana and Grafana Enterprise 12.4.0 to 12.4.14. Versions 10.1.0 to 12.3.11 are also affected; they are end of life and will not receive a fix. On Grafana 13.x the fix ships in the Elasticsearch data source plugin; see the plugin section. 

Affected platforms: 

Self-managed (on-premise)
