CVE-2026-42402 Details
Description
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.
A denial-of-service vulnerability has been identified in Apache Neethi versions prior to 3.2.2. The issue arises from algorithmic complexity in the policy normalization process, where specially crafted WS-Policy documents can cause an exponential increase in memory usage. This occurs due to an unbounded Cartesian cross-product expansion, leading to excessive policy alternatives being generated and ultimately exhausting the JVM heap. Users are advised to upgrade to version 3.2.2, which addresses this issue by limiting the maximum number of normalized policy alternatives.
Users should upgrade to Apache Neethi version 3.2.2 or later.
