Description
A Git server that Grafana's Git Sync (provisioning) is configured to use can exhaust Grafana's memory by returning oversized or highly compressed responses (uncontrolled resource consumption). Exploitation requires an administrator to have configured Git Sync with that server.
Weaknesses (CWE)
- CWE-770 — Allocation of Resources Without Limits or Throttling
