Miggo AIRoot Cause Analysis

  1. The commit adds validation to lib/ping.ts's ping function, confirming it was the injection point.
  2. The vulnerability description explicitly mentions both lib/ui/api.ts and lib/ping.ts as vulnerable components.
  3. The CWE-78 mapping indicates direct OS command injection, which occurs when building the ping command string.
  4. The 'unauthorized' aspect in the description points to missing auth checks in the API layer (lib/ui/api.ts).
  5. Pre-patch code shows host input was only processed with replace() calls, insufficient for security validation.
