Detailsinfo

A vulnerability, which was classified as critical, was found in Rapid7 Velociraptor up to 0.74.6/0.75.6/0.76.1. Affected is an unknown part of the component Client Monitoring Message handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Rapid7 Velociraptor versions prior to 0.76.2 contain an improper input validation vulnerability in the client monitoring message handler on the Velociraptor server (primarily Linux) that allows an authenticated remote attacker to write to arbitrary internal server queues via a crafted monitoring message with a malicious queue name. The server handler that receives client monitoring messages does not sufficiently validate the queue name supplied by the client, allowing a rogue client to write arbitrary messages to privileged internal queues. This may lead to remote code execution on the Velociraptor server. Rapid7 Hosted Velociraptor instances are not affected by this vulnerability.

The advisory is available at docs.velociraptor.app. This vulnerability is traded as CVE-2026-5329 since 04/01/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The technical details are unknown and an exploit is not available.

Upgrading to version 0.76.2 eliminates this vulnerability.
