Attack profile from CVSS 3.1 · CNA. Fix status from CNA and Red Hat. Impact type from CWE-770.

Summary

Grafana OSS and Grafana Enterprise from 13.0.0 before 13.0.11, from 13.1.0 before 13.1.8, and from 13.2.0 before 13.2.4 are affected, as is the Nanogit package before 1.7.0. A Git server that Grafana's Git Sync provisioning is configured to use can return oversized or highly compressed responses, and Grafana allocates memory for them without limits (CWE-770), which exhausts its memory. Exploitation requires an administrator to have configured Git Sync with that server.

Description from the CNA

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.
