Advisory Summary

CVE-2026-18860 is a HIGH (CVSS 8.7) security vulnerability vulnerability (CWE-280: Improper Handling of Insufficient Permissions or Privileges) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not handle or incorrectly handles when it has insufficient privileges to access resources or functionality as specified by their permissions. this may cause it to follow unexpected code paths that may leave the product in an invalid state.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-18860

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-2026-18860, 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-280: Improper Handling of Insufficient Permissions or Privileges, where the product does not handle or incorrectly handles when it has insufficient privileges to access resources or functionality as specified by their permissions. this may cause it to follow unexpected code paths that may leave the product in an invalid state. 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

Velociraptor allows multi-tenant deployments named "Orgs". By default Velociraptor, uses the ROOT org, but users can create child orgs for other tenants within the same deployment. Users can have different permissions in each org. To manage Orgs, Velociraptor usually examines the ORG_ADMIN permission on the ROOT org. This issue results from the Velociraptor server allowing for the deletion of Orgs by incorrectly checking the ORG_ADMIN permission of callers within the calling ORG instead of the ROOT org. However, Org admins of child orgs were able to add this permission to their ACL token within their own org. This allows an administrator in a child org, which is not also an administrator in the ROOT org, to delete other orgs.
