CVE-2026-42403: CWE-400 Uncontrolled Resource Consumption in Apache Software Foundation Apache Neethi
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.
AI Analysis
Technical Summary
CVE-2026-42403 is a high-severity vulnerability in Apache Neethi caused by improper detection of circular references in WS-Policy documents. When a policy references another policy that in turn references the original, the normalization process can loop indefinitely or recurse excessively, leading to stack overflow or application hang. This uncontrolled resource consumption (CWE-400) can be exploited remotely without authentication to cause a denial of service. The vendor recommends upgrading to version 3.2.2 to fix this issue.
Potential Impact
Successful exploitation results in denial of service due to application hang or stack overflow caused by infinite loops or excessive recursion during policy normalization. There is no impact on confidentiality or integrity reported. The vulnerability can be triggered remotely without privileges or user interaction.
Mitigation Recommendations
Users should upgrade Apache Neethi to version 3.2.2, which contains the fix for this vulnerability. No other mitigations or temporary workarounds are provided. Patch status is not explicitly stated in the vendor advisory, but the recommendation to upgrade indicates an official fix is available.
