CVE-2026-6290Network attack vector

Cross-organization access via reused ACL token

Published Apr 15, 2026 · Updated Apr 15, 2026

Incorrect authorization in Rapid7 Velociraptor 0.76 before 0.76.3 and 0.75 before 0.75.8 allows remote authenticated users to query other orgs. The server-side query() plugin accepts a target organization while reusing the notebook user's current ACL token instead of verifying access to that organization. Exposure requires a Linux deployment that relies on organization separation to restrict untrusted GUI users; resulting queries retain the user's source-organization permissions.
