Advisory Summary

CVE-2026-8919 is a HIGH security vulnerability vulnerability (CWE-942: Permissive Cross-domain Security Policy with Untrusted Domains) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses a web-client protection mechanism such as a content security policy (csp) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-8919

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-8919, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-942: Permissive Cross-domain Security Policy with Untrusted Domains, where the product uses a web-client protection mechanism such as a content security policy (csp) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Permissive Cross-domain Security Policy with Untrusted Domains in ASUS GameSDK allows a remote user to obtain a local user’s NTLM hash by convincing the user to visit a crafted web page that sends a request containing a UNC path to the application’s local service endpoint. This can result in information disclosure or data tampering, may cause GameSDK to become unavailable, and may also enable access to the victim’s information on other services. Refer to the ' Security Update for ASUS GameSDK  ' section on the ASUS Security Advisory for more information.
