What is CVE-2022-23496?

CVE-2022-23496 is a high-severity security vulnerability in nl.basjes.parse.useragent:yauaa (maven), affecting versions >= 7.0.0, < 7.9.0. It is fixed in 7.9.0.

How severe is CVE-2022-23496?

CVE-2022-23496 has a CVSS score of 8.6 (High). 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 packages are affected by CVE-2022-23496?

nl.basjes.parse.useragent:yauaa (maven) versions >= 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, = 7.0.0, < 7.9.0.

Is there a fix for CVE-2022-23496?

Yes. CVE-2022-23496 is fixed in 7.9.0. Upgrade to this version or later.

Is CVE-2022-23496 exploitable, and should I be worried?

Whether CVE-2022-23496 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-2022-23496 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.

How do I fix CVE-2022-23496?

Summary

Yauaa vulnerable to ArrayIndexOutOfBoundsException triggered by a crafted Sec-Ch-Ua-Full-Version-List

Workarounds

Catch and discard any exceptions from Yauaa.

Impact

Applications using the Client Hints analysis feature introduced with 7.0.0 can crash because the Yauaa library throws an ArrayIndexOutOfBoundsException. Applications that do not use this feature are not affected.

CVE-2022-23496 has a CVSS score of 8.6 (High). The vector is network-reachable, no 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 (7.9.0); upgrading removes the vulnerable code path.

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.
