GHSA-4724-7jwc-3fpw is a medium-severity (CVSS 6.7) Cross-site Scripting (XSS) vulnerability in github.com/grafana/grafana. O3 Security confirms whether GHSA-4724-7jwc-3fpw is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Grafana Spoofing originalUrl of snapshots
Real-World Exposure
github.com/grafana/grafana🐹github.com/grafana/grafanaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
To create a snapshot (and insert an arbitrary URL) the built-in role Viewer is sufficient. When a dashboard is shared as a local snapshot, the following three fields are offered in the web UI for a user to fill out: • Snapshotname • Expire • Timeout(seconds) After the user confirms creation of the snapshot (i.e. clicks the ”Local Snapshot” button) an HTTP POST request is sent to the Grafana server. The HTTP request contains additional parameters that are not visible in the web UI. The parameter originalUrl is not visible in the web UI, but sent in the HTTP POST request.
The value of the originalUrl parameter is automatically generated. The purpose of the presented originalUrl parameter is to provide a user that views the snapshot the possibility to click on the button in the Grafana web UI and be presented with the dashboard that the snapshot was made out of.
The value of the originalUrl parameter can be arbitrarily chosen by a malicious user that creates the snapshot (Note: by editing the query thanks to a web proxy like Burp) When another user opens the URL of the snapshot, they will be presented with the regular web interface delivered by the trusted Grafana server. The issue here is that the ”Open original dashboard” button no longer points to the to the real original dashboard but to the attacker’s (injected) URL.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/grafana/grafana | ≥ 9.0.0&&< 9.2.8 | 9.2.8 |

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. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/grafana/grafana to 9.2.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4724-7jwc-3fpw 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 pinpoints whether GHSA-4724-7jwc-3fpw is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-4724-7jwc-3fpw. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-4724-7jwc-3fpw in your dependencies?
O3 detects GHSA-4724-7jwc-3fpw across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
