Miggo AIRoot Cause Analysis

The vulnerability stems from path processing sequence where:

  1. Authentication checks occur on the original URL (including fake endings)
  2. Path gets normalized/stripped after authentication
  3. Routing uses the modified path

This creates a mismatch between the authenticated path and executed path. The PKIAuthenticationPlugin.authenticate method would appear in runtime profiles during exploitation as it's the entry point for authentication decisions using the vulnerable path handling. The JIRA ticket SOLR-17417 and reproduction steps confirm the authentication bypass occurs through path manipulation handled by this plugin.
