Doc Text:	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.	Story Points:	---

Description OSIDB Bzimport 2026-05-01 10:01:19 UTC

Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy normalization. Specially crafted WS-Policy documents can trigger an exponential Cartesian cross-product expansion during the normalization process, causing unbounded memory allocation that exhausts the JVM heap. This occurs when the normalization process generates an excessive number of policy alternatives without bounds, leading to runtime memory exhaustion.

Users should upgrade to 3.2.2 which limits the maximum number of normalized policy alternatives.
