Severity by source
Network-reachable DoS with no confidentiality/integrity impact; AC:H because exploitation is gated on the app normalizing attacker-supplied (not trusted/static) policy documents.

Exponential re-expansion of repeated policy references in Apache Neethi before 3.2.4 lets a remote attacker exhaust CPU and memory during WS-Policy normalization, causing denial of service. The flaw is reachable only when an application feeds an attacker-controlled WS-Policy document into Neethi's normalization routine; deployments that normalize only static or locally configured policies are not exposed, and the assessed CVSS:3.1 vector (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H) rates this as a high-impact availability-only issue with no confidentiality or integrity effect. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the application pass an ATTACKER-CONTROLLED WS-Policy document into Apache Neethi's policy normalization routine; the crafted document uses repeated policy references that cause exponential re-expansion. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a pure availability issue (denial of service) in Apache Neethi, the Java WS-Policy framework. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Apache Neethi 3.2.4, which the vendor identifies as the release that fixes the exponential reference re-expansion; because Neethi is usually a transitive dependency, confirm the resolved org.apache.neethi:neethi version in every deployed artifact rather than relying on a direct dependency declaration, and see https://ws.apache.org/ and https://seclists.org/oss-sec/2026/q3/831 for the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify every application that feeds WS-Policy documents from untrusted or external sources into Apache Neethi and confirm the deployed version; for those services, apply immediate input controls at the gateway (reject or severely cap externally supplied policy documents, limit reference depth), enable CPU and memory alerting, and ensure container or process resource quotas prevent host-level exhaustion. …
