CVE-2026-19072: Velociraptor Investigator reaches SuperUser via hunt EffectivePrincipal
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 "compiledcollectorargs" 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.

Frequently Asked Questions
What access must an attacker already have?
The attacker must be able to schedule a hunt. The advisory identifies the minimal required role as Investigator.
What can an attacker do after exploiting this issue?
An Investigator can supply compiled VQL for a hunt in a way that bypasses the ACL checks normally applied to artifacts. This can allow arbitrary VQL statements to run as an administrator user on the Velociraptor server.
