Privileged queue writes via unchecked queue name
Published Apr 9, 2026 · Updated Apr 9, 2026
Improper input validation in affected Rapid7 Velociraptor releases allows remote authenticated users to write privileged internal server queues. The client monitoring handler accepts a crafted queue name and routes attacker-controlled messages into privileged queues without sufficient validation. A rogue enrolled client is required; affected Linux server builds end at 0.74.6, 0.75.6, and 0.76.4, and hosted instances are excluded.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=0.74.6
- Affected versionversion=0 <=0.75.6
- Affected versionversion=0 <=0.76.1
