Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: The UPLC runtime virtual machine is susceptible to panics when processing malformed PlutusData or mismatched builtin constants. If untrusted execution scripts trigger these panic vectors (such as unreachable!() statements), it results in immediate Denial of Service for the executing node.
Auth Bypass: Flaws in type checking logic, specifically regarding Data casting and assertion-free structural bypasses, have allowed unbound types to skip key validator safeguards, leading to logical bypasses of validator assertions.
Access Control: Compiler optimization passes that clean up unused bindings risked silently eliminating critical runtime state validations (such as 'expect' declarations), leading to optimized binaries that skip mandatory runtime checks.
