Miggo AIRoot Cause Analysis

The vulnerability stems from the use of static cryptographic parameters in PasswordPlaceholderConfigurer. Both encrypt() and decrypt() functions initialize the cipher with hardcoded values (key/IV), as confirmed by the CVE description and patch references. The patches (PR#1781/PR#1782) likely address this by making these parameters configurable. The functions are explicitly tied to the insecure encryption mechanism described.
