CVE-2026-66143: Uncontrolled Resource Consumption

It is possible to bypass the maximum number of normalized policy alternatives that was introduced in Apache Neethi 3.2.2 via certain crafted policies, which may lead to a denial of service attack via resource consumption. Users are recommended to upgrade to version 3.2.3, which fixes this issue...

PT-2026-64288

Name of the Vulnerable Software and Affected Versions Apache Neethi versions prior to 3.2.3 Description Uncontrolled recursion occurs when parsing policies that lack policy Ids or contain deeply nested structures. This can lead to a denial of service attack resulting from runtime memory exhaustio...

PT-2026-64289

Name of the Vulnerable Software and Affected Versions Apache Neethi versions 3.2.2 through 3.2.2 Description Certain crafted policies can bypass the maximum number of normalized policy alternatives, potentially leading to a denial of service attack through excessive resource consumption...

Summary IBM App Connect Enterprise is vulnerable to multiple vulnerabilities due to Apache HttpClient and Apache Neethi. Vulnerability Details CVEID:CVE-2026-40542 DESCRIPTION: Missing critical step in authentication in Apache HttpClient 5.6 allows an attacker to cause the client to accept...

Security Bulletin: IBM App Connect for Healthcare is vulnerable to multiple vulnerabilities due to Apache Log4j and Apache Neethi

Summary IBM App Connect for Healthcare is vulnerable to multiple vulnerabilities due to Apache Log4j and Apache Neethi. Vulnerability Details CVEID:CVE-2026-42402 DESCRIPTION: Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy normalization. Special...

org.apache.neethi: Apache Neethi: Denial of Service via circular policy references

A flaw was found in Apache Neethi. An attacker can exploit this vulnerability by crafting malicious WS-Policy documents that contain circular policy references. This can cause the policy normalization process to enter an infinite loop or excessive recursion, leading to a stack overflow or...

org.apache.neethi: Apache Neethi: Denial of Service via algorithmic complexity in policy normalization

A flaw was found in Apache Neethi. A remote attacker can exploit this vulnerability by providing specially crafted WS-Policy documents. This triggers an algorithmic complexity issue during policy normalization, leading to an exponential expansion of policy alternatives. This unbounded memory...

Security Bulletin: IBM Enterprise Build of Quarkus is affected by multiple vulnerabilities

Summary IBM Enterprise Build of Quarkus is affected by vulnerabilities in the PostgreSQL JDBC driver and Apache Neethi Vulnerability Details CVEID:CVE-2026-42402 DESCRIPTION: Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy normalization. Speciall...

CVE-2026-42402

A flaw was found in Apache Neethi. A remote attacker can exploit this vulnerability by providing specially crafted WS-Policy documents. This triggers an algorithmic complexity issue during policy normalization, leading to an exponential expansion of policy alternatives. This unbounded memory...

CVE-2026-42403

A flaw was found in Apache Neethi. An attacker can exploit this vulnerability by crafting malicious WS-Policy documents that contain circular policy references. This can cause the policy normalization process to enter an infinite loop or excessive recursion, leading to a stack overflow or...

Denial Of Service

Apache Neethi is vulnerable to Denial of Service DoS. The vulnerability is due to algorithmic complexity in the policy normalization process, where specially crafted WS-Policy documents trigger exponential Cartesian cross-product expansion, leading to excessive memory allocation and JVM heap...

Server-Side Request Forgery (SSRF)

Apache Neethi is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to lack of validation of URIs in the PolicyReference API, allowing applications to fetch policies from arbitrary protocols or internal addresses, enabling attackers to trigger outbound requests to internal o...

Denial Of Service

Apache Neethi is vulnerable to Denial of Service.The vulnerability is due to improper handling of circular references during policy normalization, where recursive policy references are not detected, leading to infinite loops or excessive recursion that can cause stack overflow or application hang...

CVE-2026-42404

A flaw was found in Apache Neethi. When an application explicitly calls the PolicyReference API to retrieve a policy from a remote Uniform Resource Identifier URI, Apache Neethi does not impose restrictions on the URI. This allows a remote attacker to cause the application to make outbound reques...

GHSA-287C-FXR7-3W6C Apache Neethi doesn't impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API

Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API. When an application explicitly calls the API to retrieve a policy from a remote URI, an outbound request is made for arbitrary protocols and internal IP...

CVE-2026-42404

Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API. When an application explicitly calls the API to retrieve a policy from a remote URI, an outbound request is made for arbitrary protocols and internal IP...

CVE-2026-42404 Apache Neethi: Unrestricted HTTP Redirect Following in Policy References
