GHSA-4x5h-xmv4-99wx
CRITICALGHSA-4x5h-xmv4-99wx is a critical-severity (CVSS 9.1) CWE-326 vulnerability in org.apache.linkis:linkis. O3 Security confirms whether GHSA-4x5h-xmv4-99wx is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache Linkis Authentication Bypass vulnerability
Real-World Exposure
org.apache.linkis:linkisReal-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 <=1.3.1, due to the default token generated by Linkis Gateway deployment being too simple, it is easy for attackers to obtain the default token for the attack. Generation rules should add random values.
We recommend users upgrade the version of Linkis to version 1.3.2 And modify the default token value. You can refer to Token authorization.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.apache.linkis:linkis | all versions | 1.3.2 |
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. 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 to 1.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4x5h-xmv4-99wx 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-4x5h-xmv4-99wx 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-4x5h-xmv4-99wx. 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-4x5h-xmv4-99wx in your dependencies?
O3 detects GHSA-4x5h-xmv4-99wx across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
