Summary
Wildfly has a memory leak vulnerability
A flaw was found in Wildfly affecting versions 19.0.0.Final, 19.1.0.Final, 20.0.0.Final, 20.0.1.Final, and 21.0.0.Final. When an application uses the OpenTracing API's java-interceptors, there is a possibility of a memory leak. This flaw allows an attacker to impact the availability of the server. The highest threat from this vulnerability is to system availability.
Impact
CVE-2020-27822 has a CVSS score of 5.9 (Medium). 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 (21.0.2.Final, 22.0.0.Beta1); 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.

Frequently Asked Questions
- What is CVE-2020-27822? CVE-2020-27822 is a medium-severity security vulnerability in org.wildfly:wildfly-parent (maven), affecting versions >= 19.0.0.Final, < 21.0.2.Final. It is fixed in 21.0.2.Final, 22.0.0.Beta1.
- How severe is CVE-2020-27822? CVE-2020-27822 has a CVSS score of 5.9 (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 org.wildfly:wildfly-parent are affected by CVE-2020-27822? org.wildfly:wildfly-parent (maven) versions >= 19.0.0.Final, < 21.0.2.Final is affected.
- Is there a fix for CVE-2020-27822? Yes. CVE-2020-27822 is fixed in 21.0.2.Final, 22.0.0.Beta1. Upgrade to this version or later.
- Is CVE-2020-27822 exploitable, and should I be worried? Whether CVE-2020-27822 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-2020-27822 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.
