The upstream vendor (Vitaly Puzrin) backported the maxTotalMergeKeys defense from v5, which prevents the O(N^2) merge-chain CPU exhaustion attack. The fix is present at lib/loader.js:155,166,384-386 and enforces a cumulative limit (default 10000) on keys processed during merge operations.

Version 4.3.0 uses the older JavaScript-based parser architecture that does not exhibit the exponential re-parsing behavior. While version 4.3.0 does process nested flow sequences with key:value pairs (the Input), its parser cannot reach the Goal (exponential CPU exhaustion) because it lacks the vulnerable code path (restoreState + re-parse pattern).",
