MEDIUM 4.9EPSS 0.34%

Does this matter?

Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.

Description

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.
