GHSA-5993-wwpg-m92c

HIGHFix: apache/ozone#1871

GHSA-5993-wwpg-m92c is a high-severity (CVSS 8.8) CWE-862 vulnerability in org.apache.hadoop:hadoop-ozone-ozone-manager. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-5993-wwpg-m92c is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

GHSA-5993-wwpg-m92c plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 0 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.hadoop:hadoop-ozone-ozone-manager. 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.

  2. Fix

    Update org.apache.hadoop:hadoop-ozone-ozone-manager to 1.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5993-wwpg-m92c is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-5993-wwpg-m92c 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-5993-wwpg-m92c. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
