CVE-2022-36062
Description
A flaw was found in Grafana. This vulnerability impacts folders/dashboards with Admin-only permissions and where role-based access control (RBAC) was ever enabled at least once. When RBAC is enabled, Grafana runs migrations that translate legacy access control permissions into RBAC permissions. The migrations contain a bug, which grants additional access to folders/dashboards that only had the Admin role grant, resulting in a privilege escalation where Editors can edit and Viewers can view the folder/dashboard to which they should not have access.
Statement
Grafana RBAC is available in Grafana Enterprise, which is not shipped in any of the Red Hat products.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
