GHSA-jx4g-3xqm-62vh is a medium-severity (CVSS 6.5) Path Traversal vulnerability in io.jmix.localfs:jmix-localfs. O3 Security confirms whether GHSA-jx4g-3xqm-62vh is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
io.jmix.localfs:jmix-localfs has a Path Traversal in Local File Storage
Real-World Exposure
io.jmix.localfs:jmix-localfs☕io.jmix.localfs:jmix-localfsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Attackers could manipulate the FileRef parameter to access files on the system where the Jmix application is deployed, provided the application server has the necessary permissions. This can be accomplished either by modifying the FileRef directly in the database or by supplying a harmful value in the fileRef parameter of the /files endpoint of the generic REST API.
Arbitrary file reading on the operating system where the Jmix process is running.
The severity of the vulnerability is mitigated by the fact that the application UI and the generic REST API are typically accessible only to authenticated users. Additionally, the /files endpoint in Jmix requires specific permissions and is disabled by default.
Workarounds

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jmix.localfs:jmix-localfs. 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 io.jmix.localfs:jmix-localfs to 1.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jx4g-3xqm-62vh 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-jx4g-3xqm-62vh 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-jx4g-3xqm-62vh. 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-jx4g-3xqm-62vh in your dependencies?
O3 detects GHSA-jx4g-3xqm-62vh across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
