CVE-2026-16491 CVE Record
Grafana’s RBAC service ignored the requested folder when checking whether a user was a folder administrator for deleted dashboard listings. A user with dashboard permission-management rights on any folder could therefore be treated as an administrator of every folder.
This could expose deleted dashboard items from folders where the user lacked administrative access. The fix requires permission on the specified folder, an ancestor, or a wildcard scope.
Cross-organization user modification and deletion via the SCIM API in Grafana Enterprise
A service account with user-management permissions in one organization can read, modify, disable or delete users belonging to other organizations on the same Grafana instance through the SCIM API (insecure direct object reference). Only Grafana Enterprise instances with SCIM enabled are affected.
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.
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.
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.
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.
