CVE-2026-91865 PUBLISHED

Apache Neethi: Crafted policy references cause exponential expansion during normalization leading to denial of service

Assigner: apache
Reserved: 15.09.2026 Published: 21.09.2026 Updated: 21.09.2026

A small WS-Policy document using repeated policy references can force Neethi to re-expand the same references exponentially during normalization, consuming huge amounts of CPU and memory (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
