Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Parsers are highly vulnerable to infinite loops and panics when processing malformed user inputs. This risk represents a class of parser-level hangs where termination conditions or bounds checks are bypassed or missing entirely during lexing.
Denial of Service: Deeply nested or self-referential language structures can trigger infinite loops or exponential resource consumption during type flattening and inference. Implementing explicit depth limits is critical to prevent CPU exhaustion.
Denial of Service: Recursive AST analysis and call-graph traversal without tracking visited states or nodes frequently leads to infinite loops when encountering recursive functional patterns.
