GHSA-mvpr-q6rh-8vrp is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in github.com/grafana/grafana. A fix is available for github.com/grafana/grafana — see the affected versions and patch details below.
Grafana XSS via a query alias for the ElasticSearch datasource
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-mvpr-q6rh-8vrp plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/grafana/grafana, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/grafana/grafana to 7.1.0-beta1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mvpr-q6rh-8vrp is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-mvpr-q6rh-8vrp can be triaged on real exposure rather than presence alone.
Tailored to GHSA-mvpr-q6rh-8vrp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
A vulnerable version of Grafana is shipped in OpenShift 3.11 - 4.5 and OpenShift ServiceMesh, however Prometheus is used as a data source and modification to Elasticsearch or Testdata requires full control of the grafana component. Access is restricted to authenticated users only by OpenShift OAuth. As OpenShift and…
