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.\n\nThis allows an administrator in one org to impersonate another user in another org, in which they may not have the IMPERSONATE permission."}], "lastModified": "2026-08-28T21:17:10.720", "sourceIdentifier": "cve@rapid7.com"}
