Miggo AIRoot Cause Analysis

The vulnerability stems from improper mapping of SCM changelog authors to email addresses without validating Jenkins user existence. Based on standard plugin structure and vulnerability patterns:

  1. Mailer$DescriptorImpl.getRecipients would handle recipient resolution logic
  2. CoreMailer.collectEmailAddresses would aggregate addresses from changelog data These functions likely contained the vulnerable email mapping logic described in the advisory, where local-part matching without user validation occurred. The medium confidence reflects inference from vulnerability characteristics without direct patch access.
