Overview

org.apache.struts:struts2-core is a popular open-source framework for developing web applications in the Java programming language.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to improper handling of getProperty() by the XWorkListPropertyAccessor class.
