Miggo AIRoot Cause Analysis

The vulnerability CVE-2020-7720 and GHSA-92xj-mqp7-vmcj explicitly reference util.setPath as the entry point for prototype pollution. The GitHub commit 6a1e3ef removes this function specifically due to security concerns, and the CHANGELOG confirms the removal was motivated by the prototype pollution risk. The function's implementation in the diff shows it recursively sets properties without checking for prototype pollution vectors like 'proto'.
