<version>2.8.3</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=com.typesafe.playHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2020-27196, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=com.typesafe.playAnalyze the terminal output to locate any version of Play in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.6), your application is affected.
Note: The mvn dependency:tree -Dincludes=com.typesafe.play command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
