Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The CRDT consensus validator historically checked the identity of the forwarding peer instead of the message signer, allowing unauthorized peers to inject validated state updates into the cluster.
Denial of Service: Aborted requests on the /add endpoint could leak goroutines and keep BlockStreamer or DAGService channels open indefinitely, consuming system resources.
Auth Bypass: Follower nodes exposed the privileged RepoGCLocal RPC endpoint, allowing trusted peers to prematurely trigger local Garbage Collection and disrupt follower state.
