CVE-2026-91866: Vulnerability in Apache Software Foundation Apache Neethi
A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
AI Analysis
Technical Summary
Apache Neethi contains a vulnerability (CVE-2026-91866) where processing a specially crafted pair of WS-Policy documents triggers exponential computational work in the policy-intersection logic. This results in excessive CPU consumption, effectively causing a denial of service condition. The Apache Software Foundation has addressed this issue in version 3.2.4 of Apache Neethi.
Potential Impact
An attacker can cause a denial of service by forcing Apache Neethi to perform exponential amounts of work, leading to CPU exhaustion and degraded service availability. There is no indication of code execution or data compromise.
Mitigation Recommendations
Users should upgrade Apache Neethi to version 3.2.4 or later to remediate this vulnerability. No other mitigations are indicated.
