Official description
Apache Neethi is vulnerable to uncontrolled recursion when parsing policies that lack policy Ids or with deeply nested structures, which may lead to a denial of service attack when parsing policies due to runtime memory exhaustion. Users are recommended to upgrade to version 3.2.3, which fixes this issue.
