DescriptionCVE.org

Any Editor could delete any snapshot, even if they have no access to read or write them.

AnalysisAI

Missing authorization in Grafana OSS's snapshot deletion endpoint allows any authenticated Editor-role user to delete arbitrary snapshots across the platform, regardless of whether they hold read or write access to those snapshots. Affected versions span a wide release range from 9.4.0 through 13.0.1 across multiple major branches (CPE: cpe:2.3:a:grafana:grafana_oss). …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid Grafana session with at minimum an Editor role (confirmed by CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N scores 6.5 (Medium), reflecting network-accessible, low-complexity exploitation with a low-privilege prerequisite, yielding high integrity impact but no confidentiality or availability loss. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Grafana user holding an Editor role enumerates snapshot IDs - discoverable through Grafana's UI, API, or shared links distributed within the organization - belonging to dashboards outside their access scope. The Editor then issues a DELETE request to the Grafana snapshot API targeting one of these foreign snapshot IDs; the server processes the deletion without validating object-level permissions, successfully destroying the snapshot. …
Remediation Upgrade to the appropriate vendor-patched release for your current branch: 11.6.14+security-04, 12.2.8+security-04, 12.3.6+security-04, 12.4.3+security-02, or 13.0.1+security-01, as confirmed by Grafana's security advisory at https://grafana.com/security/security-advisories/cve-2026-28380. … Detailed patch versions, workarounds, and compensating controls in full report.
