GHSA-564w-97r7-c6p9 is a high-severity (CVSS 8.6) OS Command Injection vulnerability in livebook. O3 Security confirms whether GHSA-564w-97r7-c6p9 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Livebook Desktop's protocol handler can be exploited to execute arbitrary command on Windows
Real-World Exposure
livebook💧livebookReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Hex packages — download data is not available via public APIs for these ecosystems.
Description
On Windows, it is possible to open a livebook:// link from a browser which opens Livebook Desktop and triggers arbitrary code execution on victim's machine.
Any user using Livebook Desktop on Windows is potentially vulnerable to arbitrary code execution when they expect Livebook to be opened from browser.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💧Hex | livebook | ≥ 0.8.0&&< 0.8.2 | 0.8.2 |
| 💧Hex | livebook | ≥ 0.9.0&&< 0.9.3 | 0.9.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for livebook. 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 livebook to 0.8.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-564w-97r7-c6p9 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-564w-97r7-c6p9 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-564w-97r7-c6p9. 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-564w-97r7-c6p9 in your dependencies?
O3 detects GHSA-564w-97r7-c6p9 across Hex dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
