9.9 · CRITICALOverview
CVE-2025-11539 is a critical-severity vulnerability. It was published on October 9, 2025 and has a CVSS 3.1 base score of 9.9 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.9, rated CRITICAL. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical 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.
