Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Failing to propagate errors when loading accounts in the blocklist validator allows blocked transactions to bypass execution checks, undermining the platform's access control guarantees.
Denial of Service: Consensus proposal streaming that relies on unbounded structures (like primitive HashMaps) is vulnerable to memory exhaustion attacks from untrusted network peers.
Path Traversal: Extracting archives within arcup without verifying destination paths allows malicious archives to write files to arbitrary locations on the host system.
