CVE-2025-11539 – Arbitrary Code Execution in Grafana Image Renderer Plugin

CVE ID : CVE-2025-11539

Published : Oct. 9, 2025, 8:15 a.m. | 22 minutes ago

Description : Grafana Image Renderer is vulnerable to remote code execution due to an arbitrary file write vulnerability. This is due to the fact that the /render/csv endpoint lacked validation of the filePath parameter that allowed an attacker to save a shared object to an arbitrary location that is then loaded by the Chromium process.

Instances are vulnerable if:

1. The default token (“authToken”) is not changed, or is known to the attacker.
2. The attacker can reach the image renderer endpoint.
This issue affects grafana-image-renderer: from 1.0.0 through 4.0.16.

Severity: 9.9 | CRITICAL
