• CVE-2023-0594: 9.22% estimated exploitation activity in the next 30 days; percentile 95.35 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Grafana is an open-source platform for monitoring and observability. Starting with the 7.0 branch, Grafana had a stored XSS vulnerability in the trace view visualization. The stored XSS vulnerability was possible due the value of a span's attributes/resources were not properly sanitized and this will be rendered when the span's attributes/resources are expanded. An attacker needs to have the Editor role in order to change the value of a trace view visualization to contain JavaScript. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard. Users may upgrade to version 8.5.21, 9.2.13 and 9.3.8 to receive a fix.

# Patch Next advisory brief: CVE-2023-0594

Advisory: Grafana vulnerable to Cross-site Scripting
IDs: CVE-2023-0594, GHSA-xw5p-hw8j-xg4q
Record: https://patchnext.com/advisories/cve-2023-0594 (revision 1, source checked 26 Oct 2026, 14:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
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 9.3.8, 9.2.13, 8.5.21. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/grafana/grafana: affected >= 7.0.0, < 8.5.21; >= 9.0.0, < 9.2.13; >= 9.3.0, < 9.3.8; fixed in 8.5.21, 9.2.13, 9.3.8

## 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-xw5p-hw8j-xg4q (GitHub-reviewed advisory GHSA-xw5p-hw8j-xg4q lists affected ranges: Go github.com/grafana/grafana >=7.0.0 =9.0.0 =9.3.0 <9.3.8)
