Security readout for executives and security teams
Plain-English summary
CVE-2026-10601 is a medium-severity Grafana OSS issue in the Tempo and Loki data source plugins. A low-privileged Viewer user may send crafted requests that reach backend endpoints they should not access. Business impact depends on backend configuration and may include internal response leakage, credential exposure, or unintended backend actions.
Executive priority
Treat this as a moderate-priority authenticated exposure issue. It is not currently supported as actively exploited in the provided sources, but organizations using affected Grafana versions with Loki or Tempo should remediate promptly because backend configuration can raise business impact.
Technical view
The issue is classified as CWE-22 path traversal. In affected Grafana OSS versions, Tempo and Loki data source plugin request handling can allow a Viewer-authenticated user to access unintended backend endpoints. The CVSS 3.1 score is 5.4 with low attack complexity and required low privileges.
Likely exposure
Exposure is most likely where Grafana OSS 11.6.0, 12.2.0, 12.3.0, 12.4.0, or 13.0.0 is deployed with Tempo or Loki data sources configured and Viewer users present.
Exploitation context
The source bundle does not show CISA KEV listing or cited active exploitation. Exploitation requires authenticated Viewer permissions and specially crafted requests. Impact varies with the configured backend and what endpoints or credentials are reachable through the affected data source plugins.
Researcher notes
Evidence is limited to the CVE source bundle and Grafana advisory reference. The bundle names affected versions and impact categories but does not provide exploit details, fixed versions, or specific mitigations. Avoid assuming exposure unless Loki or Tempo data sources and Viewer-accessible users are present.
Mitigation direction
- Check Grafana’s advisory for fixed versions or vendor-approved remediation.
- Prioritize upgrading affected Grafana OSS versions once vendor guidance confirms the target release.
- Limit Viewer access to Grafana instances using Loki or Tempo data sources.
- Review Loki and Tempo backend permissions exposed to Grafana data source integrations.
- Rotate exposed data source credentials if investigation suggests unauthorized backend access.
Validation and detection
- Inventory Grafana OSS versions and compare against the affected version list.
- Confirm whether Loki or Tempo data sources are configured on affected instances.
- Review Grafana access logs for unusual data source plugin request patterns.
- Assess backend configuration for sensitive administrative or credential-bearing endpoints.
- Verify remediation by confirming Grafana version and data source access controls.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
