CVE-2026-95502
Description
A flaw was found in Grafana. A malicious or compromised Git server configured for Git Sync provisioning can return oversized or highly compressed responses, causing uncontrolled memory consumption. This issue can exhaust system memory, resulting in a Denial of Service (DoS) condition on the Grafana instance. Exploitation requires an administrator to have configured Git Sync to communicate with the untrusted server.
Statement
This issue is rated Moderate. If an administrator configures Grafana Git Sync against a malicious or compromised Git server, oversized or highly compressed responses can exhaust Grafana memory and cause a denial of service. Confidentiality and integrity are not affected. Exploitation depends on administrator-configured Git Sync to an untrusted server, which limits practical exposure. Upstream affects Grafana 13.0.x before 13.0.11, 13.1.x before 13.1.8, and 13.2.x before 13.2.4; Red Hat streams shipping Grafana 12.x or earlier are not affected.
Mitigation
Do not point Git Sync at untrusted Git servers; use only trusted repositories and credentials. Restrict who can configure Git Sync and limit Grafana management-plane network exposure. Apply process or cgroup memory limits to contain memory-exhaustion impact.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
