What is CVE-2022-40152?

CVE-2022-40152 is a medium-severity out-of-bounds write vulnerability in com.fasterxml.woodstox:woodstox-core (maven), affecting versions >= 6.0.0, < 6.4.0. It is fixed in 6.4.0, 5.4.0. A write operation targets a memory location beyond the intended buffer boundary.

How severe is CVE-2022-40152?

CVE-2022-40152 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of com.fasterxml.woodstox:woodstox-core are affected by CVE-2022-40152?

com.fasterxml.woodstox:woodstox-core (maven) versions >= 6.0.0, < 6.4.0 is affected.

Is there a fix for CVE-2022-40152?

Yes. CVE-2022-40152 is fixed in 6.4.0, 5.4.0. Upgrade to this version or later.

Is CVE-2022-40152 exploitable, and should I be worried?

Whether CVE-2022-40152 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2022-40152 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

Denial of Service due to parser crash

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.

Impact

A write operation targets a memory location beyond the intended buffer boundary. Typical impact: memory corruption, crash, or arbitrary code execution.

CVE-2022-40152 has a CVSS score of 6.5 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (6.4.0, 5.4.0); upgrading removes the vulnerable code path.

Affected versions

com.fasterxml.woodstox:woodstox-core (>= 6.0.0, < 6.4.0) com.fasterxml.woodstox:woodstox-core (< 5.4.0)

Security releases

com.fasterxml.woodstox:woodstox-core → 6.4.0 (maven) com.fasterxml.woodstox:woodstox-core → 5.4.0 (maven)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
