Description

A flaw was found in Grafana. This flaw allows a malicious user with the authorization to log into a Grafana instance via a configured OAuth IdP to take over an existing Grafana account under certain conditions.

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).
