CVE-2026-42403Apache Neethi: Circular Policy Reference Infinite Loop
High 7.5
In plain English
A high-severity uncontrolled resource consumption in Apache Neethi from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.8% (higher than 56% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
