Why this deserves its current priority

CVSS is 7.5. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.

Analysis status

Analysis pending evidence review

Factual feed record only; HOL analysis is not approved for indexing. Read the methodology.

Affected scope and exposure questions

The current feed maps grafana/grafana (generic). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
PackageAffected rangeFixed version
grafana/grafanageneric>=8.0.0 <8.0.7 || >=8.1.0 <8.1.8 || >=8.2.0 <8.2.7 || = 8.3.08.0.7, 8.1.8, 8.2.7

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for grafana/grafana.
  2. 2Review the reported fix. Update grafana/grafana to 8.0.7 if you use the affected versions. Test the change in a non-production environment first.
