Grafana OSS Alertmanager Templates Test Endpoint Uncontrolled Resource Consumption

The alertmanager templates test endpoint (/api/alertmanager/grafana/config/api/v1/templates/test) can execute templates with no memory limits. Mass-executing templates in a short period causes OOM and crashes the Grafana service. The endpoint requires very low privileges and is exploitable with anonymous access enabled.

CWE-400Jul 23, 2026
CVSS5.3v3.1EPSS0.198%PoCs0SignalsSTIX

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).

CWE-79Jul 10, 2026
CVSS6.8v3.1EPSS0.24%PoCs0SignalsSTIX

Pre-authentication denial of service via 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).

CWE-400Jul 10, 2026
CVSS5.3v3.1EPSS0.397%PoCs0SignalsSTIX

Denial of service via unbounded request body size

Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service.

CWE-400Jul 10, 2026
CVSS7.5v3.1EPSS0.388%PoCs0SignalsSTIX

Cross-Organization Public Dashboard Deletion via Missing Org Isolation

The public dashboard deletion endpoint does not enforce organization isolation, allowing an Org Admin in one organization to delete public dashboards belonging to a different organization by supplying the target dashboard's identifiers.

CWE-284Jul 7, 2026
CVSS3.1v3.1EPSS0.136%PoCs0SignalsSTIX

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

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.

CWE-400CWE-770Jun 22, 2026
CVSS7.5v3.1EPSS0.432%PoCs0SignalsSTIX

Stored XSS in the Geomap panel tile-layer attribution

A user with Editor permissions can place a malicious script in the attribution field of a Geomap panel's XYZ tile layer via a template variable. The script then executes in the browser of any user who views the affected dashboard (stored cross-site scripting).

CWE-79Jun 22, 2026
CVSS7.3v3.1EPSS0.251%PoCs0SignalsSTIX

Path traversal in the Tempo and Loki data source plugins

A user with Viewer permissions can use specially crafted requests to the Tempo and Loki data source plugins to reach unintended backend endpoints. Depending on the backend configuration this can expose data source credentials, leak internal responses, or trigger administrative actions on the configured backend.

CWE-22Jun 22, 2026
CVSS5.4v3.1EPSS0.258%PoCs0SignalsSTIX

Path traversal in the Loki data source plugin

A user with Viewer permissions can use a path traversal in the Loki data source plugin to reach administrative Loki endpoints and read sensitive backend configuration and internal service information.

CWE-22Jun 22, 2026
CVSS7.7v3.1EPSS0.443%PoCs0SignalsSTIX

IDOR in Annotations API allows unprivileged users to DELETE annotation

Editors could delete any annotation, even those they do not have read access to. The editor user cannot create or read the annotations.

CWE-284May 13, 2026
CVSS4.3v3.1EPSS0.198%PoCs0SignalsSTIX

Grafana Data Source Plugin: DoS (OOM) via Negative Interval Injection in $__timeGroup Macro

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.

CWE-400May 13, 2026
CVSS6.5v3.1EPSS0.328%PoCs0SignalsSTIX

Grafana plugin resources can lead to unbounded memory allocation

A request to the Grafana plugin resources endpoint can cause unbounded memory allocation by reading the entire request body into memory. An authenticated user can exploit this to trigger an out-of-memory condition, potentially causing a denial of service.

CWE-770May 13, 2026
CVSS6.5v3.1EPSS0.328%PoCs0SignalsSTIX

Auth Proxy IPv6 whitelist bypass

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.

CWE-1188May 13, 2026
CVSS7.4v3.1EPSS0.282%PoCs0SignalsSTIX

SQL Expressions Read File From Disk

A vulnerability in SQL Expressions allows an authenticated attacker to read arbitrary files from the Grafana server's filesystem. Only instances with the sqlExpressions feature toggle enabled are vulnerable.

CWE-552May 13, 2026
CVSS6.3v3.1EPSS0.366%PoCs0SignalsSTIX

BAC in Snapshot API allows deletion of unauthorized dashboard snapshots

Any Editor could delete any snapshot, even if they have no access to read or write them.

CWE-862May 13, 2026
CVSS6.5v3.1EPSS0.227%PoCs0SignalsSTIX

Users can generate Service Account tokens after permissions removal

When a user's access to mint tokens for a service account is revoked, it is sometimes still possible to do so for a few seconds after the event. The user will eventually lose access to do this.

CWE-284May 13, 2026
CVSS5.9v3.1EPSS0.343%PoCs0SignalsSTIX

Dashboard Import Overwrites ACL — Editor Privilege Escalation to Dashboard Admin

An Editor can overwrite a dashboard not owned by them to acquire admin on that specific dashboard. The user must have write access to the dashboard to escalate privilege.

CWE-284CWE-287May 13, 2026
CVSS7.1v3.1EPSS0.226%PoCs0SignalsSTIX

Grafana Live push endpoint allows unbounded memory allocation leading to OOM

The Grafana Live push endpoint can be exploited to cause unbounded memory allocation by sending a large or streaming request body, potentially leading to out-of-memory conditions. An authenticated user with access to the Grafana Live API can trigger this issue.

CWE-770May 13, 2026
CVSS6.5v3.1EPSS0.328%PoCs0SignalsSTIX

Viewer-triggered race condition in Grafana Live leads to complete server crash

A race condition in Grafana Live allows authenticated users with Viewer role to trigger a server crash by sending concurrent requests that cause a fatal map access error. This results in complete service unavailability requiring restart of the Grafana server.

CWE-362May 13, 2026
CVSS6.5v3.1EPSS0.262%PoCs0SignalsSTIX

Missing Protected-field Authorization in Provisioning Contact Points API

A vulnerability has been discovered in Grafana OSS where an authorization bypass in the provisioning contact points API allows users with Editor role to modify protected webhook URLs without the required alert.notifications.receivers.protected:write permission.

CWE-285Mar 26, 2026
CVSS5.4v3.1EPSS0.238%PoCs0SignalsSTIX

Grafana MSSQL Data Source Plugin: Restriction Bypass Leading to OOM DoS

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.

CWE-400Mar 26, 2026
