GHSA-7jqv-fw35-gmx9
MEDIUMGHSA-7jqv-fw35-gmx9 is a medium-severity (CVSS 6.5) vulnerability in nbconvert. O3 Security confirms whether GHSA-7jqv-fw35-gmx9 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
nbconvert has an Arbitrary File Read via Path Traversal in HTMLExporter Image Embedding
Real-World Exposure
nbconvertReal-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
Summary
When HTMLExporter.embed_images=True, nbconvert's markdown renderer allows arbitrary file read via path traversal in image references. A malicious notebook can exfiltrate sensitive files from the conversion host by embedding them as base64 data URIs in the output HTML.
Patches
Upgrade to nbconvert 7.17.1
Workarounds
Do not enable HTMLExporter.embed_images (it is not enabled by default).
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | nbconvert | ≥ 6.5.0&&< 7.17.1 | 7.17.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nbconvert. 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 nbconvert to 7.17.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7jqv-fw35-gmx9 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-7jqv-fw35-gmx9 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-7jqv-fw35-gmx9. 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-7jqv-fw35-gmx9 in your dependencies?
O3 detects GHSA-7jqv-fw35-gmx9 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
