CVE-2026-21727 1 Grafana 2 Grafana, Grafana Correlations 2026-04-24 3.3 Low
--- title: Cross-Tenant Legacy Correlation Disclosure and Deletion draft: false hero: image: /static/img/heros/hero-legal2.svg content: "# Cross-Tenant Legacy Correlation Disclosure and Deletion" date: 2026-01-29 product: Grafana severity: Low cve: CVE-2026-21727 cvss_score: "3.3" cvss_vector: "CVSS:3.3/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N" fixed_versions: - ">=11.6.11 >=12.0.9 >=12.1.6 >=12.2.4" --- A cross-tenant isolation vulnerability was found in Grafana’s Correlations feature affecting legacy correlation records. Due to a backward compatibility condition allowing org_id = 0 records to be returned across organizations, a user with datasource management privileges could read and permanently delete legacy correlation data belonging to another organization. This issue affects correlations created prior to Grafana 10.2 and is fixed in >=11.6.11, >=12.0.9, >=12.1.6, and >=12.2.4. Thanks to Gyu-hyeok Lee (g2h) for reporting this vulnerability.
CVE-2026-27879 1 Grafana 1 Grafana 2026-04-24 6.5 Medium
A resample query can be used to trigger out-of-memory crashes in Grafana.
CVE-2026-21720 1 Grafana 2 Grafana, Grafana Enterprise 2026-04-24 7.5 High
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.
CVE-2026-28377 1 Grafana 1 Tempo 2026-04-24 7.5 High
A vulnerability in Grafana Tempo exposes the S3 SSE-C encryption key in plaintext through the /status/config endpoint, potentially allowing unauthorized users to obtain the key used to encrypt trace data stored in S3. Thanks to william_goodfellow for reporting this vulnerability.
CVE-2026-21722 1 Grafana 2 Grafana, Grafana Enterprise 2026-04-24 5.3 Medium
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.
CVE-2026-21724 1 Grafana 1 Grafana 2026-04-24 5.4 Medium

CVE-2026-27876 1 Grafana 2 Grafana, Grafana Enterprise 2026-04-24 9.1 Critical
A chained attack via SQL Expressions and a Grafana Enterprise plugin can lead to a remote arbitrary code execution impact (RCE). This is enabled by a feature in Grafana (OSS), so all users are always recommended to update to avoid future attack vectors going this path. Only instances with the sqlExpressions feature toggle enabled are vulnerable. Only instances in the following version ranges are affected: - 11.6.0 (inclusive) to 11.6.14 (exclusive): 11.6.14 has the fix. 11.5 and below are not affected. - 12.0.0 (inclusive) to 12.1.10 (exclusive): 12.1.10 has the fix. 12.0 did not receive an update, as it is end-of-life. - 12.2.0 (inclusive) to 12.2.8 (exclusive): 12.2.8 has the fix. - 12.3.0 (inclusive) to 12.3.6 (exclusive): 12.3.6 has the fix. - 12.4.0 (inclusive) to 12.4.2 (exclusive): 12.4.2 has the fix. 13.0.0 and above also have the fix: no v13 release is affected.
CVE-2026-28375 1 Grafana 1 Grafana 2026-04-24 6.5 Medium
A testdata data-source can be used to trigger out-of-memory crashes in Grafana.
CVE-2026-21725 1 Grafana 1 Grafana 2026-04-24 2.6 Low
A time-of-create-to-time-of-use (TOCTOU) vulnerability lets recently deleted-then-recreated data sources be re-deleted without permission to do so. This requires several very stringent conditions to be met: - The attacker must have admin access to the specific datasource prior to its first deletion. - Upon deletion, all steps within the attack must happen within the next 30 seconds and on the same pod of Grafana. - The attacker must delete the datasource, then someone must recreate it. - The new datasource must not have the attacker as an admin. - The new datasource must have the same UID as the prior datasource. These are randomised by default. - The datasource can now be re-deleted by the attacker. - Once 30 seconds are up, the attack is spent and cannot be repeated. - No datasource with any other UID can be attacked.
CVE-2025-12141 1 Grafana 1 Grafana 2026-04-20 6.5 Medium
In Grafana's alerting system, users with edit permissions for a contact point, specifically the permissions “alert.notifications:write” or “alert.notifications.receivers:test” that are granted as part of the fixed role "Contact Point Writer", which is part of the basic role Editor - can edit contact points created by other users, modify the endpoint URL to a controlled server. By invoking the test functionality, attackers can capture and extract redacted secure settings, such as authentication credentials for third-party services (e.g., Slack tokens). This leads to unauthorized access and potential compromise of external integrations.
CVE-2025-6197 1 Grafana 1 Grafana 2026-04-15 4.2 Medium
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
CVE-2024-8118 1 Grafana 1 Grafana 2026-04-15 4.7 Medium
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.
CVE-2024-6322 1 Grafana 2 Grafana, Grafana Enterprise 2026-04-15 4.4 Medium
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.
CVE-2025-3260 1 Grafana 1 Grafana 2026-04-15 8.3 High
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.
CVE-2025-6023 1 Grafana 1 Grafana 2026-04-15 7.6 High
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.
