MEDIUMCVE-2020-11110 is a medium-severity (CVSS 5.4) 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 stored XSS
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
CVE-2020-11110 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 377,238 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.
Real-World Exposure

Description
Grafana through 6.7.1 allows stored XSS due to insufficient input protection in the originalUrl field, which allows an attacker to inject JavaScript code that will be executed after clicking on Open Original Dashboard after visiting the snapshot.

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 6.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-11110 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 CVE-2020-11110 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2020-11110. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect CVE-2020-11110
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id cve-2020-11110 -u https://target- Template
- Grafana <= 6.7.1 - Cross-Site Scripting
- Severity
- medium
- Impact
- Successful exploitation of this vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser, leading to potential data theft or unauthorized actions.
- Remediation
- This issue can be resolved by updating Grafana to the latest version.

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.
Both OpenShift 3.11 and 4.x grafana-container's package a vulnerable version of grafana. However the grafana instance is set to read-only meaning that the potential XSS attack cannot be performed because the original url field cannot be modified. Access to the grafana panel is additionally behind OpenShift OAuth proxy…
