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.
