CVE-2026-66142: Apache Neethi

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

Apache Neethi is vulnerable to uncontrolled recursion when parsing policies that lack policy Ids or with deeply nested structures, which may lead to a denial of service attack when parsing policies due to runtime memory exhaustion. Users are recommended to upgrade to version 3.2.3, which fixes this issue.

Affected products

• Apache Neethi: before 3.2.3 (fixed in 3.2.3)
