CVE-2026-42127 (GCVE-0-2026-42127)
Vulnerability from cvelistv5 – Published: 2026-06-22 16:31 – Updated: 2026-06-22 17:28
VLAI
Title
Grafana pre-auth DoS through arbitrarily large input to public dashboard query handler
Summary
The public dashboard query endpoint does not limit request body size before processing, allowing unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily large JSON payloads. This can lead to denial of service through memory exhaustion. No valid dashboard access token or authentication is required to exploit this vulnerability.

Title
Stored XSS via Geomap Panel Template Variable Attribution Injection
Summary
The geomap panel's XYZ tile layer has a sanitize-then-interpolate ordering bug. sanitizeTextPanelContent() runs on the raw template string before getTemplateSrv().replace() substitutes the variable value, which uses the glob format with no HTML escaping. The result is passed to OpenLayers via element.innerHTML. An Editor can set a textbox variable's default value to an XSS payload that executes for every user who opens the dashboard. This is a bypass of the CVE-2023-0507 fix

Title
Path Traversal in Tempo and Loki Data Source Plugins — Credential Leakage and Admin Endpoint Access
Summary
The Tempo and Loki datasource plugins construct backend HTTP requests by interpolating user-supplied input into URL paths without sanitization, enabling path traversal. A Viewer-role user can: (1) capture admin-configured datasource credentials (secureJsonData custom headers) by traversing to an attacker-controlled endpoint, (2) invoke state-changing admin endpoints on Tempo (e.g. /flush, /shutdown), and (3) exfiltrate internal service data via Loki's CallResource which returns full HTTP response bodies.

Title
Path Traversal in Loki Datasource leads to Internal Information Disclosure
Summary
The Loki datasource plugin's callResource handler contains a path traversal vulnerability. An authenticated Viewer-role user can escape the plugin's resource sandbox and access administrative Loki endpoints (e.g. /config, /services, /ready) to extract sensitive backend configuration and internal service information.

Title
Tempo TraceQL query with exemplar hint could result in unbounded memory usage
Summary
A TraceQL query in Grafana Tempo with a large exemplars hint value can cause the Tempo instance to allocate an excessive amount of memory, resulting in an out-of-memory crash. This could allow an authenticated user to trigger a denial of service against the Tempo service.

CVE-2026-11769 (GCVE-0-2026-11769)
Vulnerability from cvelistv5 – Published: 2026-06-13 04:17 – Updated: 2026-06-16 12:01

Title
Operator - Namespaced User Path Traversal
Summary
We have released version 5.24.0 of the Grafana Operator. This patch includes a CRITICAL severity security fix for a path traversal/privilege escalation vulnerability in the Grafana Operator.
### Summary
The Grafana Operator supports loading dashboards & library panels using the jsonnet data templating language. The jsonnet expression is evaluated in the context of the operator manager pod.
### Impact
It is possible for a malicious user who can create Dashboard or LibraryPanel resources for a Grafana instance to obtain the Kubernetes service account token of the Grafana Operator manager.
### Affected versions
All Grafana Operator versions <= 5.23
### Solutions and mitigations
All installations should be upgraded as soon as possible.
As a workaround, the following ValidatingAdmissionPolicy prevent the creation or modification of jsonnet based resources:
apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicy
metadata:
name: "prevent-jsonnet-dashboards"
spec:
failurePolicy: Fail
matchConstraints:
resourceRules:
- apiGroups: ["grafana.integreatly.org"]
apiVersions: ["v1beta1"]
operations: ["CREATE", "UPDATE"]
resources: ["grafanadashboards", "grafanalibrarypanels"]
validations:
- expression: "!has(object.spec.jsonnetLib)"
---
apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicyBinding
metadata:
name: "prevent-jsonnet-dashboards-clusterwide"
spec:
policyName: "prevent-jsonnet-dashboards"
validationActions: [Deny]
### Acknowledgement
We would like to thank Artem Cherezov for responsibly disclosing the vulnerability.

Title
Grafana Data Source Plugin: DoS (OOM) via Negative Interval Injection in $__timeGroup Macro
Summary
Using the $__timeGroup macro, one can achieve an OOM by overloading the server. This requires a SQL datasource. If the server is set up to auto-restart, the impact is minimal or non-existent, as the attack can take upwards of half an hour to crash the server.

Title
Grafana plugin resources can lead to unbounded memory allocation

Title
Auth Proxy IPv6 whitelist bypass
Summary
When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses. Addresses specifying a mask explicitly are not affected; to mitigate easily, add the desired mask (usually /128) to the addresses. Only auth proxy is affected; Okta, SAML, LDAP, etc are unaffected here.

Title
Tempo query limit results in unbounded memory allocation
Summary
Tempo queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy.
Mitigation can be done by setting max_result_limit in the search config, e.g. to 262144 (2^18).

CVE-2026-11769 (GCVE-0-2026-11769)
Vulnerability from nvd – Published: 2026-06-13 04:17 – Updated: 2026-06-16 12:01
VLAI
Title
Operator - Namespaced User Path Traversal
Summary
We have released version 5.24.0 of the Grafana Operator. This patch includes a CRITICAL severity security fix for a path traversal/privilege escalation vulnerability in the Grafana Operator.
### Summary
The Grafana Operator supports loading dashboards & library panels using the jsonnet data templating language. The jsonnet expression is evaluated in the context of the operator manager pod.
### Impact
It is possible for a malicious user who can create Dashboard or LibraryPanel resources for a Grafana instance to obtain the Kubernetes service account token of the Grafana Operator manager.
### Affected versions
All Grafana Operator versions <= 5.23
### Solutions and mitigations
All installations should be upgraded as soon as possible.
As a workaround, the following ValidatingAdmissionPolicy prevent the creation or modification of jsonnet based resources:
apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicy
metadata:
name: "prevent-jsonnet-dashboards"
spec:
failurePolicy: Fail
matchConstraints:
resourceRules:
- apiGroups: ["grafana.integreatly.org"]
apiVersions: ["v1beta1"]
operations: ["CREATE", "UPDATE"]
resources: ["grafanadashboards", "grafanalibrarypanels"]
validations:
- expression: "!has(object.spec.jsonnetLib)"
---
apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicyBinding
metadata:
name: "prevent-jsonnet-dashboards-clusterwide"
spec:
policyName: "prevent-jsonnet-dashboards"
validationActions: [Deny]
### Acknowledgement
We would like to thank Artem Cherezov for responsibly disclosing the vulnerability.

Grafana Data Source Plugin: DoS (OOM) via Negative Interval Injection in $__timeGroup Macro
Summary
Using the $__timeGroup macro, one can achieve an OOM by overloading the server. This requires a SQL datasource. If the server is set up to auto-restart, the impact is minimal or non-existent, as the attack can take upwards of half an hour to crash the server.

CVE-2026-33376 (GCVE-0-2026-33376)
Vulnerability from nvd – Published: 2026-05-13 19:28 – Updated: 2026-06-22 16:31

Title
Auth Proxy IPv6 whitelist bypass
Summary
When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses. Addresses specifying a mask explicitly are not affected; to mitigate easily, add the desired mask (usually /128) to the addresses. Only auth proxy is affected; Okta, SAML, LDAP, etc are unaffected here.

Title
Tempo query limit results in unbounded memory allocation
Summary
Tempo queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy.
Mitigation can be done by setting max_result_limit in the search config, e.g. to 262144 (2^18).
