How severe is CVE-2024-1459?

CVE-2024-1459 has a CVSS score of 5.3/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2024-1459?

CVE-2024-1459 affects the following packages: io.undertow:undertow-core (Maven), io.undertow:undertow-core (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-1459?

Update io.undertow:undertow-core to 2.2.31.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-1459 is resolved across your whole dependency graph.

How do I detect CVE-2024-1459 in my Maven dependencies?

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

How do I mitigate CVE-2024-1459 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-2024-1459?

O3 pinpoints whether CVE-2024-1459 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-2024-1459 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-1459 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-2024-1459?

CVE-2024-1459 has an EPSS (Exploit Prediction Scoring System) score of 1.7%, placing it in the 74th 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-2024-1459 published, and has it been updated?

CVE-2024-1459 was published on February 12, 2024 and was last updated on March 15, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
