CVE-2026-42403 is a denial-of-service vulnerability in Apache Neethi versions before 3.2.2. Improper detection of circular references in WS-Policy definitions allows a crafted document containing mutually referencing policies to trigger an infinite loop or excessive recursion during policy normalization. Processing such a document can cause a stack overflow or application hang.
