CVE-2026-19583— Velociraptor Required Permissions bypass by using client monitoring queries
Quick assessment
Affected
Rapid7 Velociraptor
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Velociraptor 允许通过额外的权限来控制部分敏感工件（artifacts）。例如， 工件允许在端点执行任意命令，因此其调度需要 权限。然而，对于客户端监控工件（client monitoring artifacts）未实现类似的权限检查。此外，客户端监控工件也没有被要求必须携带 类型。这使得任何能够调度客户端监控工件的用户，也能调度原本受到限制的工件（如 ）。

Vulnerability Title
Velociraptor Required Permissions bypass by using client monitoring queries
Source: CVE Program / CVE List V5
Vulnerability Description
Velociraptor allows some sensitive artifacts to be gated by additional permissions. For example, the Linux.Sys.BashShell artifact allows arbitrary command execution on endpoints, and so it requires the EXECVE permission to schedule. However, no such check was implemented for client monitoring artifacts. Additionally there was no requirement that client monitoring artifacts carry the CLIENT_EVENTS type. This allows any user who can schedule client monitoring artifacts to also schedule otherwise restricted artifacts (such as Linux.Sys.BashShell).
