Miggo AIRoot Cause Analysis

The vulnerability stems from unencrypted storage of credentials in Jenkins' XML configuration files. In Jenkins plugin architecture:

  1. Credential fields are typically managed through setter methods that bind UI input to configuration objects
  2. XML serialization is handled by XStream or similar frameworks
  3. The explicit lack of encryption indicates missing credential masking or secure storage mechanisms

Though no patch is available, the pattern matches Jenkins' configuration handling:

  • The setGpgPassphrase() would receive the plaintext value from configuration forms
  • getConfigXml() would handle persistence logic Both would fail to invoke Jenkins' credential encryption APIs like Secret.toString() or PasswordEncrypter
