Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Flaws in signature normalization and missing length validation prior to calling lower-level cryptographic recovery routines (such as secp256k1.Signature.fromCompact) can permit signature verification bypasses.
Cryptographic Issues: Signing operations that omit extra entropy or fail to normalize signatures are vulnerable to private key recovery attacks via nonce-reuse vectors.
Auth Bypass: Improper address extraction and incorrect hash serialization during transaction assembly in Tempo mode can result in failed or bypassable signature validations.
