The exponential parsing vulnerability was introduced in the TypeScript rewrite at version 5.0.0 and does not exist in the 4.x JavaScript codebase. The target uses a linear parsing architecture in readFlowCollection that parses flow sequence keys once, then parses values separately, without the restoreState+parseNode reparsing behavior that causes O(2^n) complexity. Empirical testing confirms the pathological input (nested flow sequence pairs) completes in 3ms on 4.2.0 versus minutes on vulnerable 5.x versions.",
