Miggo AIRoot Cause Analysis

  1. The vulnerability description explicitly names the set() function. The commit diff shows prototype pollution guards added to both set() and transform() functions.
  2. The Snyk PoC demonstrates exploitation via set(), and the test cases in the commit show added protections against 'proto' manipulation in both set() and transform().
  3. The code analysis reveals both functions process user-controlled paths/keys without initial 'proto' validation, enabling prototype property injection prior to patching.
