Recurring patterns

Cryptographic Signature Verification Bypass: Failure to evaluate the return value of zero-knowledge proof verification logic (such as grootle.verify) allows attackers to bypass core validation rules and submit invalid transaction proofs.

Integer Overflow: Unchecked addition of input values allows transaction value manipulation, leading to the creation of massive numbers of unexpected coins or the bypass of maximum limit checks.

Denial of Service: Unhandled exceptions during validation or deserialization of complex cryptographic types (e.g., Lelantus, Sigma, or Spark structures) can crash nodes, facilitating remote network-wide outages.
