Which packages are affected by CVE-2022-40152?

CVE-2022-40152 affects the following packages: com.fasterxml.woodstox:woodstox-core (Maven), com.fasterxml.woodstox:woodstox-core (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-40152?

Update com.fasterxml.woodstox:woodstox-core to 6.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-40152 is resolved across your whole dependency graph.

How do I detect CVE-2022-40152 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.fasterxml.woodstox:woodstox-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2022-40152 if there is no patch (or I can't update yet)?

Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Is CVE-2022-40152 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2022-40152, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2022-40152?

CVE-2022-40152 has an EPSS (Exploit Prediction Scoring System) score of 18.2%, placing it in the 97th 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 warrants monitoring and prompt remediation.

Real-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

Those using FasterXML/woodstox to seralize XML data may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. This effect may support a denial of service attack.

This vulnerability is only relevant for users making use of the DTD parsing functionality.
