No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

Velociraptor's VQL has a query() plugin which allows running a VQL query in a different org or user context. To be able to run as a different user, the calling user needs to have the IMPERSONATE permission (usually only given to administrators). Velociraptor versions prior to 0.77.2 evaluate this permission against the caller's org instead of against the target org.

This allows an administrator in one org to impersonate another user in another org, in which they may not have the IMPERSONATE permission.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (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.
