  1. CVE-2026-9703 7.1 Élevée

    Grafana Enterprise · Grafana OSS

    Grafana's data source proxy did not apply role-based access control to write requests forwarded to Loki data sources. A user holding only the Viewer role on an affected Grafana instance could send POST, PUT and DELETE requests through the proxy to the Loki rules API (/loki/api/v1/rules), allowing them to create, modify and delete Loki alerting rules. Because those rules are stored by Loki rather than by Grafana, the change took effect for every user of that Loki data source, not only for the Viewer who made the request. Exploitation requires an authenticated Viewer account on the Grafana instance and a configured Loki data source; no other privileges are needed. Both Grafana OSS and Grafana Enterprise are affected. The defect is in Grafana's data source proxy; Loki itself is not vulnerable and does not need to be patched.

  2. CVE-2026-95502 5.3 Moyenne

    Grafana Nanogit · Grafana OSS · Grafana Enterprise

    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.

  3. CVE-2026-93294 6.3 Moyenne

    Grafana Enterprise · Grafana OSS

    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.

  4. CVE-2026-33374 6.5 Moyenne

    Grafana Enterprise · Grafana OSS

    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.

  5. CVE-2026-15577 6.5 Moyenne

    Grafana Enterprise · Grafana OSS

    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.
