CVE-2026-12933

grafana: RECORDED QUERIES REMOTE-WRITE VALIDATION COULD USE DATA SOURCE CREDENTIALS BEFORE CHECKING PERMISSIONS

A flaw was found in Grafana. The Recorded Queries remote-write target creation endpoint validates target connections using elevated credentials before verifying whether the caller has permission to access the underlying data source. An authenticated attacker with organization editor privileges can exploit this flaw to send authenticated HTTP requests to arbitrary paths on a connected data source host and infer sensitive information from upstream responses.

CVE-2026-81843

Memory exhaustion denial of service in Elasticsearch data source index patterns

Grafana is an open-source platform for monitoring and observability. When an Elasticsearch data source is configured with a time-based index pattern, Grafana generated one index name for every interval in the requested query time range without any upper limit. A user with permission to query the data source, which includes users holding only the Viewer role in a default configuration, could submit a single small query with an extreme time range and cause the server to allocate memory until it was terminated. The allocation occurred before any request was sent to Elasticsearch, so the condition applied whether or not the Elasticsearch cluster was reachable. Data sources configured with a static index name are not affected.

CVE-2026-107365

Unintended API access through the Google Cloud Monitoring data source resource proxy

A user with query access to a Google Cloud Monitoring data source can use its resource proxy to send requests to other Cloud Monitoring API paths with the data source's credentials, and read data from any project those credentials can reach. When the data source forwards the user's OAuth identity or uses Workload Identity Federation, the impact depends on that credential's permissions. Fixed in Google Cloud Monitoring plugin 12.6.7.

CVE-2026-106475

Elasticsearch data source resource proxy allows arbitrary methods and paths with the data source's credentials

The Elasticsearch data source resource proxy forwards the request method and path to Elasticsearch using the data source's own credentials, without restricting them to the operations the plugin needs. A user who can query the data source can alter index mappings or reach other indices on the cluster. [Improper authorization / path validation]

Authorization bypass in the Git Sync provisioning jobs API

A user with the Editor role could delete, move, push or pull Git Sync managed resources in folders where they only had view access, by creating a provisioning job through the jobs resource API, which skipped the folder permission checks (incorrect authorization).

Cross-instance user impersonation through image renderer JWTs

When independent Grafana instances share the same [rendering] renderer_token, an image renderer key issued by one instance is accepted by the others, so a user on one instance could act as the user with the same ID on another (origin validation error). This affects instances with the renderAuthJWT feature toggle enabled, the default from Grafana 13.0.0.

A user who can create Git Sync provisioning jobs (the Editor role by default) could delete or move files outside the configured repository path with a job that references a resource whose source path contains ../ sequences (path traversal). With a local filesystem repository on versions before 13.0.4 and 13.1.1, this reached files on the Grafana host.

CVE-2026-9703

Viewer role can create, modify and delete Loki alerting rules

Grafana's data source proxy did not apply role-based access control to write requests forwarded to Loki data sources. A user holding only the Viewer role on an affected Grafana instance could send POST, PUT and DELETE requests through the proxy to the Loki rules API (/loki/api/v1/rules), allowing them to create, modify and delete Loki alerting rules. Because those rules are stored by Loki rather than by Grafana, the change took effect for every user of that Loki data source, not only for the Viewer who made the request. Exploitation requires an authenticated Viewer account on the Grafana instance and a configured Loki data source; no other privileges are needed. Both Grafana OSS and Grafana Enterprise are affected. The defect is in Grafana's data source proxy; Loki itself is not vulnerable and does not need to be patched.
