Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Multiple independent fixes show a systemic pattern of missing key/owner/spender validation before state-changing EVM operations, allowing unauthorized token or allowance modifications.
Signature Verification Bypass: Block stream and record file acceptance historically lacked cryptographic verification or had weak consensus checks, risking acceptance of forged data. Multiple fixes add or correct signature verification.
Denial of Service: Recurring unbounded resource consumption across parsing, tracing, streaming, and parameter conversion; each fix adds a size/depth/concurrency/overflow limit.
