There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A user with Viewer permissions can use a path traversal in the Loki data source plugin to reach
    administrative Loki endpoints and read sensitive backend configuration and internal service information.
    (CVE-2026-42129)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A user with Editor permissions can place a malicious script in the attribution field of a Geomap panel's
    XYZ tile layer via a template variable. The script then executes in the browser of any user who views the
    affected dashboard (stored cross-site scripting). (CVE-2026-9029)

  - A user with Editor permissions can craft a dashboard whose table (TableNG) panel contains a malicious
    field name that executes as a script in the browser of any user who views the dashboard (stored cross-site
    scripting). (CVE-2026-8595)

  - 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 (denial of
    service). (CVE-2026-8609)

  - A user with Viewer permissions can use specially crafted requests to the Tempo and Loki data source
    plugins to reach unintended backend endpoints. Depending on the backend configuration this can expose data
    source credentials, leak internal responses, or trigger administrative actions on the configured backend.
    (CVE-2026-10601)
