CVE-2021-28125
MEDIUMCVE-2021-28125 is a medium-severity (CVSS 6.1) Open Redirect vulnerability in superset. O3 Security confirms whether CVE-2021-28125 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Open Redirect in Apache Superset
Real-World Exposure
superset🐍apache-supersetReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Apache Superset up to and including 1.0.1 allowed for the creation of an external URL that could be malicious. By not checking user input for open redirects the URL shortener functionality would allow for a malicious user to create a short URL for a dashboard that could convince the user to click the link.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | superset | all versions | No fix |
| 🐍PyPI | apache-superset | all versions | 1.1.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for superset. 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
No patched version of superset has shipped for CVE-2021-28125 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
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 CVE-2021-28125 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 CVE-2021-28125. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2021-28125 in your dependencies?
O3 detects CVE-2021-28125 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
