CVE-2023-5245
HIGHCVE-2023-5245 is a high-severity (CVSS 7.5) Path Traversal vulnerability in ml.combust.mleap:mleap-runtime_2.12. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2023-5245 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Using MLeap for loading a saved model (zip archive) can lead to path traversal/arbitrary file creation and possibly remote code execution.
Blast Radius
ml.combust.mleap:mleap-runtime_2.12Real-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
FileUtil.extract() enumerates all zip file entries and extracts each file without validating whether file paths in the archive are outside the intended directory.
When creating an instance of TensorflowModel using the saved_model format and an exported tensorflow model, the apply() function invokes the vulnerable implementation of FileUtil.extract().
Arbitrary file creation can directly lead to code execution

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ml.combust.mleap:mleap-runtime_2.12. 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 ml.combust.mleap:mleap-runtime_2.12 to 0.23.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-5245 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 CVE-2023-5245 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 CVE-2023-5245. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
