Commons-beanutils provides easy-to-use wrappers around Reflection and Introspection APIs
Apache Commons BeanUtils does not suppress the class property, which allows for the manipulation of the ClassLoader.
Remote attackers could potentially execute arbitrary code with the privileges of the process.
There is no known workaround at this time.
All Commons BeanUtils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=dev-java/commons-beanutils-1.9.2"
