Grafana 12.3.1 → 12.3.11

Vulnerabilities fixed by this upgrade

• 5.3 CVE-2026-8609 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 (de…
• 7.5 CVE-2026-33382 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 all…
• 3.1 CVE-2026-28378 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 supply…
• 7.5 CVE-2026-42127 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 p…
• 6.5 CVE-2026-28380 Any Editor could delete any snapshot, even if they have no access to read or write them.
• 6.5 CVE-2026-28383 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-…
• 7.4 CVE-2026-33376 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 /1…
• 7.1 CVE-2026-33377 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.
• 6.5 CVE-2026-33378 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 th…
• 6.3 CVE-2026-33380 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 v…
• 5.9 CVE-2026-33381 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.
• 4.3 CVE-2026-28374 Editors could delete any annotation, even those they do not have read access to. The editor user cannot create or read the annotations.
• 6.5 CVE-2026-28376 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…
• 6.5 CVE-2026-28379 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 s…
• 3.3 CVE-2026-21727 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…
• 6.5 CVE-2026-33375 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, cr…
• 5.4 CVE-2026-21724 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 re…
• 5.3 CVE-2026-21722 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 visi…
• 6.8 CVE-2025-41117 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…
• 8.1 CVE-2026-21721 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 dashboa…
