CVE-2026-42402

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.

Summary		(es) Apache Neethi es vulnerable a un ataque de denegación de servicio a través de la complejidad algorítmica en la normalización de políticas. Documentos WS-Policy especialmente diseñados pueden desencadenar una expansión exponencial del producto cartesiano durante el proceso de normalización, causando una asignación de memoria ilimitada que agota el heap de la JVM. Esto ocurre cuando el proceso de normalización genera un número excesivo de alternativas de política sin límites, lo que lleva al agotamiento de la memoria en tiempo de ejecución. Los usuarios deben actualizar a 3.2.2, que limita el número máximo de alternativas de política normalizadas.
