Description

A flaw was found in Apache Neethi. A remote attacker can exploit this vulnerability by providing specially crafted WS-Policy documents. This triggers an algorithmic complexity issue during policy normalization, leading to an exponential expansion of policy alternatives. This unbounded memory allocation exhausts the Java Virtual Machine (JVM) heap, resulting in a Denial of Service (DoS) condition.
