# CVE-2021-41244: Grafana Fine-grained access control vulnerability

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 2.9% , percentile 87: FIRST’s model estimates a 2.9% chance of exploitation activity in the next 30 days, higher than 87% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes github.com/grafana/grafana (Go) >= 8.0.0, < 8.2.4, fixed in 8.2.4 . Check your lockfile, including transitive dependencies.

## What it is

Grafana is an open-source platform for monitoring and observability. In affected versions when the fine-grained access control beta feature is enabled and there is more than one organization in the Grafana instance admins are able to access users from other organizations. Grafana 8.0 introduced a mechanism which allowed users with the Organization Admin role to list, add, remove, and update users’ roles in other organizations in which they are not an admin. With fine-grained access control enabled, organization admins can list, add, remove and update users' roles in another organization, where they do not have organization admin role. All installations between v8.0 and v8.2.3 that have fine-grained access control beta enabled and more than one organization should be upgraded as soon as possible. If you cannot upgrade, you should turn off the fine-grained access control using a feature flag.

## Affected packages

- Go `github.com/grafana/grafana` >= 8.0.0, < 8.2.4 → fixed: 8.2.4

## Affected products (CVE record)

- grafana grafana: >= 8.0.0, < 8.2.4

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- FIRST EPSS (model of 2026-10-21): 2.89% probability of exploitation activity in the next 30 days; percentile 87.
