CVE-2026-42403 Details
Description
Apache Neethi does not properly detect circular references in policy definitions. When a WS-Policy document contains circular policy references (where Policy A references Policy B which references Policy A), the policy normalization process can enter an infinite loop or cause excessive recursion, leading to a stack overflow or application hang. An attacker can craft malicious policy documents with circular references to cause a Denial of Service condition Users are recommended to upgrade to version 3.2.2, which fixes this issue.
A denial-of-service vulnerability exists in Apache Neethi versions prior to 3.2.2 due to improper detection of circular references in WS-Policy documents. This flaw allows an attacker to create policy documents with circular references that can cause the policy normalization process to enter an infinite loop or create excessive recursion. This behavior can lead to a stack overflow or cause the application to hang.
Users are advised to upgrade to Apache Neethi version 3.2.2 or later, which addresses this vulnerability.
