JavaScriptJavaScriptMiggo AIRoot Cause AnalysisThe vulnerability stemmed from how TypedArray deserialization handled constructor resolution. The pre-patch version in index.js used GLOBAL[val.ctorName], letting attackers specify any global function as a constructor. The patch replaced this with a strict allowlist check (TYPED_ARRAY_CTORS), confirming the vulnerable pattern was in fromSerializable. The added test case GHSA-hw46-vg6w-88fj demonstrates RCE via nested constructor abuse, which this function enabled.
