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.

CVE-2026-42403 [HIGH] CWE-606 org.apache.neethi: Apache Neethi: Denial of Service via circular policy references
org.apache.neethi: Apache Neethi: Denial of Service via circular policy references
A flaw was found in Apache Neethi. An attacker can exploit this vulnerability by crafting malicious WS-Policy documents that contain circular policy references. This can cause the policy normalization process to enter an infinite loop or excessive recursion, leading to a stack overflow or application hang. Consequently, a remote attacker can trigger a Denial of Service (DoS) condition.
Statement: This Moderate flaw in Apache Neethi allows a remote attacker to trigger a Denial of Service condition. By crafting malicious WS-Policy documents with circular references, an attacker can cause the policy normalization process to enter an infinite loop or excessive recursion, leading to application instability or a
