CVE-2026-19583: Velociraptor Required Permissions bypass by using client monitoring queries
Noroxi assessment
Priority: Monitor (action score 39/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.59% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Rapid7 Velociraptor 0.77.2.
Low priority for now. Upgrade to Rapid7 Velociraptor 0.77.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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).
