AI Analysis

Impact

A malicious Git server can cause Grafana’s Git Sync provisioning process to consume excessive memory by returning oversized or heavily compressed data, leading to uncontrolled resource consumption and possible denial of service.

Affected Systems

Grafana Enterprise, Grafana OSS, and Nanogit are susceptible. No specific version range is listed, so all current installations using Git Sync with an external server are potentially vulnerable.

Risk and Exploitability

The CVSS score of 5.3 indicates a moderate severity. EPSS is not provided, and the vulnerability is not listed in CISA KEV. Exploitation requires an administrator to have configured Git Sync with the target Git server; the attack vector is limited to environments where such configuration exists.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Restrict Git Sync to trusted Git servers and remove or isolate any untrusted repositories
  • Configure Grafana to enforce limits on response size and compression when fetching from Git servers
  • Apply any official Grafana update that addresses memory exhaustion in Git Sync
