An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

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.

An upstream fix is merged but not yet in a tagged release. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines until it ships, then apply the release.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
