CVE-2026-106475Grafana Elasticsearch Datasource path traversal
CVE-2026-106475 is a path traversal in Grafana Elasticsearch Datasource, rated high (7.1 on CVSS 3.1).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Awaiting Analysis
What it is
A file name from the request can climb out of the intended folder with sequences like ../, reaching files the service never meant to expose. A permission check exists but gets the answer wrong for some callers.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.
What an attacker gains
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker read or write files outside the folders the service meant to expose. The damage can spread past the vulnerable component into others.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade Grafana Elasticsearch Datasource to 12.9.6 or later. Other affected products have their own fixed versions on this page.
- Until it is patched, review who holds accounts that can reach it.
Description from NVD
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]
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- File storage the service can read or write. The flaw sits between the application and the file system it can reach.
- Permission checks in APIs and admin surfaces. The flaw sits between one role or tenant and another.
- Multi-tenant services. The flaw sits between one role or tenant and another.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
- Between the application and the file system it can reach. An attacker who crosses it can read or write files outside the folders the service meant to expose.
- Between one role or tenant and another. An attacker who crosses it can reach data or actions their role should not allow.
Questions to answer about your own systems
- Where does Grafana Elasticsearch Datasource run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
