Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability report explicitly identifies makePathPattern in lib/patterns.js as the affected function. The commit diff shows the fix changed the splitting logic from .split('') to .split(/*+/), which collapses consecutive asterisks. This confirms the original implementation created inefficient regex patterns by splitting on every individual '' character, creating redundant quantifiers. The added test case with '/*****************************************************************************.js$' demonstrates the ReDoS scenario the patch addresses.
