CVE-2026-42403
Apache Neethi: Circular Policy Reference Infinite Loop
CVSS Score
7.5
EPSS Score
0.0%
EPSS Percentile
0th
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.
