An attacker can exploit this vulnerability for privilege escalation by tricking an authenticated user into inviting the attacker as a new user with high privileges.
Mitigation
Please refer to the Grafana upstream advisory for possible workarounds for this issue.
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).
