| description: | |
| go-libp2p is vulnerable to targeted resource exhaustion attacks. |
| |
| These attacks target libp2p's connection, stream, peer, and memory |
| management. An attacker can cause the allocation of large amounts of memory |
| ultimately leading to the process getting killed by the host's operating |
| system. |
| |
| While a connection manager tasked with keeping the number of connections |
| within manageable limits has been part of go-libp2p, this component was |
| designed to handle the regular churn of peers, not a targeted resource |
| exhaustion attack. |
| |
| It's recommend to update to v0.21.0 onwards to get some useful functionality |
| that will help in production environments like better metrics around |
| resource usage, Grafana dashboards around resource usage, allow list |
| support, and default autoscaling limits. |
