Incorrect oauth passthrough in Grafana Snowflake Datasource

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: From CVEorg collector

Grafana is an open-source platform for monitoring and observability. The Grafana Alerting VictorOps integration was not properly protected and could be exposed to users with Viewer permission. Fixed in versions 11.5.0, 11.4.1, 11.3.3,  11.2.6, 11.1.11, 11.0.11 and 10.4.15

Access control for plugin data sources protected by the ReqActions json field of the plugin.json is bypassed if the user or service account is granted associated access to any other data source, as the ReqActions check was not scoped to each specific datasource. The account must have prior query access to the impacted datasource.

Grafana alerting wrong permission on datasource rule write endpoint

In Grafana, the wrong permission is applied to the alert rule write API endpoint, allowing users with permission to write external alert instances to also write alert rules.

Regex DoS in Grafana Zabbix Plugin

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.

Very long unicode dashboard title or panel name can hang the frontend

In Grafana, an excessively long dashboard title or panel name will cause Chromium browsers to become unresponsive due to Improper Input Validation vulnerability in Grafana. This issue affects Grafana: before 11.6.2 and is fixed in 11.6.2 and higher.

Arbitrary Code Execution in Grafana Image Renderer Plugin

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.

grafana: Cross-Site Scripting in Grafana XY Chart Panel

The built-in XY Chart plugin is vulnerable to a DOM XSS vulnerability. A user with Editor permissions is able to modify such a panel in order to make it execute arbitrary JavaScript.

grafana: Unauthorized Data Source Access in Grafana via URL Path Manipulation

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.

grafana: Improper access control in the /api/org/users/ API endpoint

An access control vulnerability was discovered in Grafana OSS where an Organization administrator could permanently delete the Server administrator account. This vulnerability exists in the DELETE /api/org/users/ endpoint. The vulnerability can be exploited when: 1. An Organization administrator exists 2. The Server administrator is either: - Not part of any organization, or - Part of the same organization as the Organization administrator Impact: - Organization administrators can permanently delete Server administrator accounts - If the only Server administrator is deleted, the Grafana instance becomes unmanageable - No super-user permissions remain in the system - Affects all users, organizations, and teams managed in the instance The vulnerability is particularly serious as it can lead to a complete loss of administrative control over the Grafana instance.

Incorrect oauth passthrough in Grafana Databricks Datasource

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

grafana: Cross Site Scripting in Grafana

An open redirect vulnerability has been identified in Grafana OSS that can be exploited to achieve XSS attacks. The vulnerability was introduced in Grafana v11.5.0. The open redirect can be chained with path traversal vulnerabilities to achieve XSS. Fixed in versions 12.0.2+security-01, 11.6.3+security-01, 11.5.6+security-01, 11.4.6+security-01 and 11.3.8+security-01

grafana: Open Redirect in Grafana

An open redirect vulnerability has been identified in Grafana OSS organization switching functionality. Prerequisites for exploitation: - Multiple organizations must exist in the Grafana instance - Victim must be on a different organization than the one specified in the URL

SSRF in Infinity Datasource Plugin

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.

grafana: incorrect assessment of permissions across organizations

Grafana is an open-source platform for monitoring and observability. The vulnerability impacts Grafana instances with several organizations, and allows a user with Organization Admin permissions in one organization to change the permissions associated with Organization Viewer, Organization Editor and Organization Admin roles in all organizations. It also allows an Organization Admin to assign or revoke any permissions that they have to any user globally. This means that any Organization Admin can elevate their own permissions in any organization that they are already a member of, or elevate or restrict the permissions of any other user. The vulnerability does not allow a user to become a member of an organization that they are not already a member of, or to add any other users to an organization that the current user is not a member of.

Stored XSS in Grafana Text plugin

Grafana is an open-source platform for monitoring and observability. On 2023-01-01 during an internal audit of Grafana, a member of the security team found a stored XSS vulnerability affecting the core plugin "Text". The stored XSS vulnerability requires several user interactions in order to be fully exploited. The vulnerability was possible due to React's render cycle that will pass though the unsanitized HTML code, but in the next cycle the HTML is cleaned up and saved in Grafana's database. An attacker needs to have the Editor role in order to change a Text panel to include JavaScript. Another user needs to edit the same Text panel, and click on "Markdown" or "HTML" for the code to be executed. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard. This issue has been patched in versions 9.2.10 and 9.3.4.

grafana: cross site scripting

Grafana is an open-source platform for monitoring and observability. Starting with the 7.0 branch, Grafana had a stored XSS vulnerability in the trace view visualization. The stored XSS vulnerability was possible due the value of a span's attributes/resources were not properly sanitized and this will be rendered when the span's attributes/resources are expanded. An attacker needs to have the Editor role in order to change the value of a trace view visualization to contain JavaScript. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard. Users may upgrade to version 8.5.21, 9.2.13 and 9.3.8 to receive a fix.

Stored XSS in Grafana's Unified Alerting

Grafana is an open-source platform for monitoring and observability. Versions on the 8.x and 9.x branch prior to 9.0.3, 8.5.9, 8.4.10, and 8.3.10 are vulnerable to stored cross-site scripting via the Unified Alerting feature of Grafana. An attacker can exploit this vulnerability to escalate privilege from editor to admin by tricking an authenticated admin to click on a link. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch. As a workaround, it is possible to disable alerting or use legacy alerting.

FGAC API Key privilege escalation in Grafana

Grafana is an open-source platform for monitoring and observability. When fine-grained access control is enabled and a client uses Grafana API Key to make requests, the permissions for that API Key are cached for 30 seconds for the given organization. Because of the way the cache ID is constructed, the consequent requests with any API Key evaluate to the same permissions as the previous requests. This can lead to an escalation of privileges, when for example a first request is made with Admin permissions, and the second request with different API Key is made with Viewer permissions, the second request will get the cached permissions from the previous Admin, essentially accessing higher privilege than it should. The vulnerability is only impacting Grafana Enterprise when the fine-grained access control beta feature is enabled and there are more than one API Keys in one organization with different roles assigned. All installations after Grafana Enterprise v8.1.0-beta1 should be upgraded as soon as possible. As an alternative, disable fine-grained access control will mitigate the vulnerability.
