Detailsinfo

A vulnerability was found in Velociraptor up to 0.77.1 and classified as very critical. This issue affects an unknown code of the component User API. The manipulation of the argument compiled_collector_args with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Velociraptor stores the compiled VQL in the hunt object internally to avoid having to recompile the artifacts for each endpoint in the hunt. Although the field "compiled_collector_args" is an internal field, Velociraptor allowed the field to be set from a user API call. This allows another user who can schedule a hunt (minimal role of "investigator" ) to set the compiled VQL statements for the hunt bypassing any ACL checks that would normally be applied. This flaw can then be escalated to allow the "investigator" user to run arbitrary VQL statements as an administrator user on the Velociraptor server.

It is possible to read the advisory at docs.velociraptor.app. The identification of this vulnerability is CVE-2026-19072 since 08/06/2026. The exploitation is known to be easy.
