Vulnerability from github – Published: 2026-05-04 00:30 – Updated: 2026-05-04 00:30

Details

Velociraptor versions prior to 0.76.4 contain a resource exhaustion vulnerability in the server's agent control channel.

This allows a compromised or rogue Velociraptor client to crash the server via out-of-memory (OOM) by sending crafted messages through the normal client communication channel.

Severity

4.9 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
