Security readout for executives and security teams
Plain-English summary
This Grafana issue lets an unauthenticated viewer of a public dashboard read annotation history outside the dashboard’s locked time range. The source says it does not expose annotations that were not otherwise visible on that public dashboard, so the impact is limited disclosure, not system compromise.
Executive priority
Handle through normal vulnerability management with visibility-focused urgency. Prioritize internet-facing public dashboards that may contain sensitive annotations, but do not treat this as remote code execution or broad data compromise based on current evidence.
Technical view
Public dashboards with annotations enabled failed to constrain annotation queries to the dashboard’s locked time range. The CVE maps this to CWE-863 with CVSS 5.3, network-accessible, low complexity, no privileges, no user interaction, and low confidentiality impact only.
Likely exposure
Exposure is limited to Grafana public dashboards with annotations enabled. The bundle lists Grafana OSS and Grafana Enterprise versions including 9.3.0, 12.0.0, 12.2.0, and 12.3.0, but does not provide complete version-range or fix details.
Exploitation context
No active exploitation is supported by the provided sources, and the CVE is not listed as KEV. The scenario is unauthenticated remote access to public dashboard annotation history beyond the intended time window.
Researcher notes
The key boundary failure is time-range authorization for annotations on public dashboards. The source explicitly limits impact: annotations outside the locked range could be read, but only if otherwise visible on that specific public dashboard. Patch details are not present in the supplied bundle.
Mitigation direction
- Review Grafana’s advisory for affected-version and upgrade guidance.
- Inventory public dashboards with annotations enabled.
- Treat public dashboard annotation history as potentially visible.
- Reduce public dashboard or annotation exposure where business need is low.
Validation and detection
- Identify Grafana OSS and Enterprise deployments using listed affected versions.
- List public dashboards that have annotations enabled.
- Review annotation history for sensitive operational or incident context.
- Confirm vendor guidance before declaring remediation complete.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
