No CVSS score has been assigned to CVE-2014-3574 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2014-3574?

CVE-2014-3574 affects the following packages: org.apache.poi:poi (Maven), org.apache.poi:poi (Maven). Ecosystems affected: Maven.

How do I fix CVE-2014-3574?

Update org.apache.poi:poi to 3.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-3574 is resolved across your whole dependency graph.

How do I detect CVE-2014-3574 in my Maven dependencies?

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

How do I mitigate CVE-2014-3574 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2014-3574?

O3 pinpoints whether CVE-2014-3574 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2014-3574 actively exploited in the wild?

No public exploit code has been indexed for CVE-2014-3574 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2014-3574?

CVE-2014-3574 has an EPSS (Exploit Prediction Scoring System) score of 7.4%, placing it in the 94th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2014-3574 published, and has it been updated?

CVE-2014-3574 was published on September 4, 2014 and was last updated on April 16, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Apache POI before 3.10.1 and 3.11.x before 3.11-beta2 allows remote attackers to cause a denial of service (CPU consumption and crash) via a crafted OOXML file, aka an XML Entity Expansion (XEE) attack.
