GHSA-47vx-fqr5-j2gw
HIGHGHSA-47vx-fqr5-j2gw is a high-severity (CVSS 7.5) CWE-404 vulnerability in cn.hutool:hutool-core. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-47vx-fqr5-j2gw is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
HuTool vulnerable to Uncontrolled Resource Consumption
Real-World Exposure
cn.hutool:hutool-coreReal-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
A vulnerability classified as problematic was found in Dromara HuTool up to 5.8.10. This vulnerability affects unknown code of the file cn.hutool.core.util.ZipUtil.java. The manipulation leads to resource consumption. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 5.8.11 is able to address this issue. It is recommended to upgrade the affected component.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cn.hutool:hutool-core. 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 cn.hutool:hutool-core to 5.8.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-47vx-fqr5-j2gw 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-47vx-fqr5-j2gw 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-47vx-fqr5-j2gw. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
