# CVE-2022-39328: Grafana Race condition allowing privilege escalation

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (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 and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.1% , percentile 65: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 65% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes github.com/grafana/grafana (Go) >= 9.2.0, < 9.2.4, fixed in 9.2.4 . Check your lockfile, including transitive dependencies.

## What it is

Grafana is an open-source platform for monitoring and observability. Versions starting with 9.2.0 and less than 9.2.4 contain a race condition in the authentication middlewares logic which may allow an unauthenticated user to query an administration endpoint under heavy load. This issue is patched in 9.2.4. There are no known workarounds.

## Affected packages

- Go `github.com/grafana/grafana` >= 9.2.0, < 9.2.4 → fixed: 9.2.4

## Affected products (CVE record)

- grafana grafana: >= 9.2.0, < 9.2.4

## Severity

- GitHub_M CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.08% probability of exploitation activity in the next 30 days; percentile 65.
