The Grafana MSSQL data source plugin contains a logic flaw that allows a low-privileged user (Viewer) to bypass API restrictions and trigger a catastrophic Out-Of-Memory (OOM) memory exhaustion, crashing the host container.

Stack traces in Grafana's Explore Traces view can be rendered as raw HTML, and thus inject malicious JavaScript in the browser. This would require malicious JavaScript to be entered into the stack trace field. Only datasources with the Jaeger HTTP API appear to be affected; Jaeger gRPC and Tempo do not appear affected whatsoever.

Public dashboards with annotations enabled did not limit their annotation timerange to the locked timerange of the public dashboard. This means one could read the entire history of annotations visible on the specific dashboard, even those outside the locked timerange. This did not leak any annotations that would not otherwise be visible on the public dashboard.

The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.

Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems.

SCIM provisioning was introduced in Grafana Enterprise and Grafana Cloud in April to improve how organizations manage users and teams in Grafana by introducing automated user lifecycle management. In Grafana versions 12.x where SCIM provisioning is enabled and configured, a vulnerability in user identity handling allows a malicious or compromised SCIM client to provision a user with a numeric externalId, which in turn could allow to override internal user IDs and lead to impersonation or privilege escalation. This vulnerability applies only if all of the following conditions are met: - `enableSCIM` feature flag set to true - `user_sync_enabled` config option in the `[auth.scim]` block set to true

When using the Grafana Databricks Datasource Plugin, if Oauth passthrough is enabled on the datasource, and multiple users are using the same datasource at the same time on a single Grafana instance, it  could result in  the wrong user identifier being used, and information for which the viewer is not authorized being returned.  This issue affects Grafana Databricks Datasource Plugin: from 1.6.0 before 1.12.0

When using the Grafana Snowflake Datasource Plugin, if Oauth passthrough is enabled on the datasource, and multiple users are using the same datasource at the same time on a single Grafana instance, it  could result in  the wrong user identifier being used, and information for which the viewer is not authorized being returned.  This issue affects Grafana Snowflake Datasource Plugin: from 1.5.0 before 1.14.1.

Grafana Image Renderer is vulnerable to remote code execution due to an arbitrary file write vulnerability. This is due to the fact that the /render/csv endpoint lacked validation of the filePath parameter that allowed an attacker to save a shared object to an arbitrary location that is then loaded by the Chromium process. Instances are vulnerable if: 1. The default token ("authToken") is not changed, or is known to the attacker.2. The attacker can reach the image renderer endpoint. This issue affects grafana-image-renderer: from 1.0.0 through 4.0.16.

CVE-2021-43798 is a path traversal vulnerability in Grafana that allows unauthorized access to local files. This vulnerability has been exploited in the wild. No specific affected versions or patch information is provided.

Grafana is an open-source platform for monitoring and observability. Grafana-Zabbix is a plugin for Grafana allowing to visualize monitoring data from Zabbix and create dashboards for analyzing metrics and realtime monitoring.  Versions 5.2.1 and below contained a ReDoS vulnerability via user-supplied regex query which could causes CPU usage to max out. This vulnerability is fixed in version 6.0.0.

Grafana is an open-source platform for monitoring and observability. The Infinity datasource plugin, maintained by Grafana Labs, allows visualizing data from JSON, CSV, XML, GraphQL, and HTML endpoints. If the plugin was configured to allow only certain URLs, an attacker could bypass this restriction using a specially crafted URL. This vulnerability is fixed in version 3.4.1.

This vulnerability in Grafana's datasource proxy API allows authorization checks to be bypassed by adding an extra slash character in the URL path. Users with minimal permissions could gain unauthorized read access to GET endpoints in Alertmanager and Prometheus datasources. The issue primarily affects datasources that implement route-specific permissions, including Alertmanager and certain Prometheus-based datasources.

A security vulnerability in the /apis/dashboard.grafana.app/* endpoints allows authenticated users to bypass dashboard and folder permissions. The vulnerability affects all API versions (v0alpha1, v1alpha1, v2alpha1). Impact: - Viewers can view all dashboards/folders regardless of permissions - Editors can view/edit/delete all dashboards/folders regardless of permissions - Editors can create dashboards in any folder regardless of permissions - Anonymous users with viewer/editor roles are similarly affected Organization isolation boundaries remain intact. The vulnerability only affects dashboard access and does not grant access to datasources.

A vulnerability in Grafana Labs Grafana OSS and Enterprise allows Privilege Escalation allows users to gain access to resources from other organizations within the same Grafana instance via the Grafana Cloud Migration Assistant.This vulnerability will only affect users who utilize the Organizations feature to isolate resources on their Grafana instance.

Grafana contains an authentication bypass vulnerability (CVE-2021-39226) that allows both authenticated and unauthenticated users to view and delete all snapshot data. This can lead to complete loss of snapshot data. The vulnerability is known to be exploited in the wild. No specific affected versions or patch information is provided.
