CVE-2026-95502 · Severity: medium · CVSS 5.3 · Published 2026-10-13

Grafana is an observability and visualization platform that administrators can configure to sync provisioning data from Git repositories. A malicious or compromised Git server can return oversized or highly compressed responses that exhaust Grafana's memory, causing denial of service. The attack requires an administrator to have already configured Git Sync to point to the attacker's server.

## How to fix

- Fixed in 13.0.11, 13.1.8, 13.2.4

## Technical details

An uncontrolled resource consumption vulnerability in Grafana's Git Sync provisioning feature allows a Git server to exhaust memory by returning oversized or highly compressed responses that are not properly validated or rate-limited. The attack requires network access and prior administrative configuration of Git Sync pointing to the attacker-controlled server. Successful exploitation results in denial of service through memory exhaustion.

## Affected products

- Grafana Grafana versions before 13.0.11, 13.1.8, and 13.2.4
