# Patch Next advisory brief: CVE-2022-31107

Advisory: Grafana account takeover via OAuth vulnerability
IDs: CVE-2022-31107, GHSA-mx47-6497-3fv2
Record: https://patchnext.com/advisories/cve-2022-31107 (revision 1, source checked 26 Oct 2026, 15:14 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/grafana/grafana 9.0.3, 8.5.9, 8.4.10, 8.3.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/grafana/grafana: affected >= 8.4.0, < 8.4.10; >= 8.5.0, < 8.5.9; >= 9.0.0, < 9.0.3; >= 5.3.0-beta1, < 8.3.10; fixed in 8.4.10, 9.0.3, 8.5.9, 8.3.10

## Suggested inspection (read-only)
- Go github.com/grafana/grafana: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/grafana/grafana.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-mx47-6497-3fv2 (GitHub-reviewed advisory GHSA-mx47-6497-3fv2 lists affected ranges: Go github.com/grafana/grafana >=8.4.0 =8.5.0 =9.0.0 =5.3.0-beta1 <8.3.10)
