Grafana is an open-source platform for monitoring and observability. Prior to versions 8.5.16 and 9.2.8, malicious user can create a snapshot and arbitrarily choose the originalUrl parameter by editing the query, thanks to a web proxy. When another user opens the URL of the snapshot, they will be...

CSRF in Web Interface in Grafana

Grafana is an open-source platform for monitoring and observability. Affected versions are subject to a cross site request forgery vulnerability which allows attackers to elevate their privileges by mounting cross-origin attacks against authenticated high-privilege Grafana users for example,...

Grafana Plugin Extraction Zip Slip

Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when extracting plugin archives. A crafted plugin archive can chain relative symbolic link entries to escape the plugin installation directory, writing arbitrary files and an executable backend binary outside that directory...

clickhouse-datasource silently drops TLS over PDC

When the ClickHouse plugin uses Native protocol the default with PDC or secure SOCKS, it asks for TLS but the connection library ignores that and talks to ClickHouse in the clear. Username, password, queries, and results can be read on the hop after the proxy. The server certificate is never...

Token Leakage in URL Login in Grafana

Grafana is an open-source platform for monitoring and observability. Starting with the 9.1 branch, Grafana introduced the ability to search for a JWT in the URL query parameter authtoken and use it as the authentication token. By enabling the "urllogin" configuration option disabled by default, a...

User Enumeration in Login in Grafana

Grafana is an open source data visualization platform for metrics, logs, and traces. Versions prior to 9.1.8 and 8.5.14 allow one user to block another user's login attempt by registering someone else'e email address as a username. A Grafana user’s username and email address are unique fields, th...

Stored XSS in the table panel (TableNG)

A user with Editor permissions can craft a dashboard whose table TableNG panel contains a malicious field name that executes as a script in the browser of any user who views the dashboard stored cross-site scripting. Upgrade to a fixed version listed below...

Library panel can be moved into a folder without library panel create permission

An authenticated user with edit permission on one folder can move a library panel into another folder where they only have view permission, through the library elements API or the equivalent App Platform resource. The update path did not check library panel create permission on the destination...

Pre-authentication denial of service in the public dashboard query handler

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 tok...

Tempo denial of service via TraceQL exemplars hint (TraceQL query execution)

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. Tempo OSS is fixed in...

Editor can forge file-provisioning provenance on dashboards via the dashboard API

An Editor can set file-provisioning metadata the grafana.app/managedBy, grafana.app/managerId and grafana.app/sourcePath annotations when creating a dashboard through the dashboard API, because these fields were stored without an authorization check. The dashboard then appears file-provisioned, a...

Operator - Namespaced User Path Traversal

We have released version 5.24.0 of the Grafana Operator. This patch includes a MEDIUM severity security fix for a path traversal/privilege escalation vulnerability in the Grafana Operator. The Grafana Operator supports loading dashboards & library panels using the jsonnet data templating language...

Pre-authentication denial of service in the OAuth login route

An unauthenticated attacker can repeatedly call Grafana's OAuth login route with unique values, causing unbounded memory growth that can eventually exhaust memory and crash the Grafana instance denial of service. Upgrade to a fixed version listed below...

Arbitrary file read via the convert_playwright_script prompt in mcp-k6

A caller who can invoke the convertplaywrightscript prompt in mcp-k6 can pass a bare file path as the playwrightscript argument and receive the contents of any file readable by the user running the server, including SSH keys and cloud credentials in that user's home directory path traversal. The...

Tempo query limit results in unbounded memory allocation

If an attacker can submit Tempo queries with large limits, they can trigger unbounded memory allocations, which can impact the availability of the service. As a mitigation, set maxresultlimit in the search configuration for example, 262144 / 2^18 . Alternatively, automatically restart the service...

Alert rules in restricted folders disclosed via the alert rules list API

An authenticated user can list alert rules stored in folders they are not allowed to read through the alert rules API list endpoint. When the set of folders the user may read was empty, the folder restriction was dropped and every alert rule in the organization was returned. From Grafana 13.1.0,...

Git Sync memory exhaustion via a malicious Git server

A Git server that Grafana's Git Sync provisioning is configured to use can exhaust Grafana's memory by returning oversized or highly compressed responses uncontrolled resource consumption. Exploitation requires an administrator to have configured Git Sync with that server...

Unbounded memory allocation in the Prometheus rule conversion API

The Prometheus rule conversion API endpoints in Grafana do not limit request body size, allowing authenticated users to trigger unbounded memory allocations that can crash the server through out-of-memory conditions...

Azure Monitor data source resource proxy allows calls to arbitrary Azure Resource Manager APIs

A user with query access to an Azure Monitor data source can use its resource proxy to call Azure Resource Manager APIs beyond those Grafana needs, with the data source's Azure identity unintended proxy. The impact is bounded by the Azure role granted to that identity...

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...

Git Sync connection configuration can be modified with read-only access

A user or service account with read-only access to Git Sync provisioning connections can modify a connection's configuration through its status subresource incorrect authorization. On Grafana 12.4 the affected API is only available when the experimental provisioning feature toggle is enabled...
