Apache Software Foundation Apache Juneau
Apache Juneau: Unsafe reflection allows attacker-controlled class initialization during parsing
CVSS 4.0
10.0Critical
Official description
Improper control of dynamically-loaded code vulnerability in Apache Juneau. When Apache Juneau parses a value into a property of type java.lang.Class (including parameterized forms), the default class swap loaded the named class with initialization enabled, so input naming a class on the application classpath ran that class's static initializer. The impact depends on the classes present in the deployment. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue.
