GHSA-jjvc-v8gw-5255
HIGHGHSA-jjvc-v8gw-5255 is a high-severity (CVSS 7.5) Deserialization of Untrusted Data vulnerability in org.apache.linkis:linkis-datasource. O3 Security confirms whether GHSA-jjvc-v8gw-5255 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache Linkis DataSource remote code execution vulnerability
Real-World Exposure
org.apache.linkis:linkis-datasourceReal-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
In Apache Linkis <= 1.5.0, data source management module, when adding Mysql data source, exists remote code execution vulnerability for java version < 1.8.0_241. The deserialization vulnerability exploited through jrmp can inject malicious files into the server and execute them.
This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out. We recommend that users upgrade the java version to >= 1.8.0_241. Or users upgrade Linkis to version 1.6.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.linkis:linkis-datasource. 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 org.apache.linkis:linkis-datasource to 1.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jjvc-v8gw-5255 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-jjvc-v8gw-5255 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-jjvc-v8gw-5255. 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-jjvc-v8gw-5255 in your dependencies?
O3 detects GHSA-jjvc-v8gw-5255 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
