GHSA-98hq-4wmw-98w9
HIGHGHSA-98hq-4wmw-98w9 is a high-severity (CVSS 8.2) CWE-284 vulnerability in de.tum.in.ase:artemis-java-test-sandbox. 2 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-98hq-4wmw-98w9 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Arbitrary code execution in de.tum.in.ase:artemis-java-test-sandbox
Real-World Exposure
de.tum.in.ase:artemis-java-test-sandboxReal-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
Summary
Because of the missing checkLink(String) override in the SecurityManager, students can load libraries and execute arbitrary code.
Details
Using System.load(String) or System.loadLibrary(String) students can load and execute arbitrary code.
private static native void start(List<String> args);
public static void main(String[] args) {
System.load(new File("path_to_lib.so").getAbsolutePath());
start(List.of(args));
}
Adding this to the security manager (and a translation) should fix the issue:
@Override
public void checkExec(String cmd) {
try {
if (enterPublicInterface())
return;
throw new SecurityException(localized("security.error_link")); //$NON-NLS-1$
} finally {
exitPublicInterface();
}
}

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for de.tum.in.ase:artemis-java-test-sandbox. 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 de.tum.in.ase:artemis-java-test-sandbox to 1.11.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-98hq-4wmw-98w9 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-98hq-4wmw-98w9 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-98hq-4wmw-98w9. 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-98hq-4wmw-98w9 in your dependencies?
O3 detects GHSA-98hq-4wmw-98w9 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
