Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Command execution interfaces and RPC routines frequently lacked robust password requirements, allowing sensitive operations like local channel backups, payment routing, and private key operations to run unauthenticated or with dynamically cleared credentials.

Cryptographic Issues: Simplified Payment Verification (SPV) routines suffered from vulnerabilities where duplicated left-siblings in Merkle branches or valid serialized transactions placed in inner nodes could trick the verifier into accepting fabricated transaction paths.

Code Injection: The use of unsafe evaluation calls such as dynamic python eval on input parameters or arbitrary config parsers exposed the system to arbitrary code execution until they were thoroughly deprecated.
