Affected versions of this package are vulnerable to Incorrect Authorization via the /api/settings/database endpoint, which allows exporting the entire database including plaintext API keys, OAuth tokens, and sensitive settings, as well as importing arbitrary data that can overwrite all existing records. An attacker can gain access to confidential information and completely replace the database contents by authenticating with any valid JWT or CLI token, which may be easily obtained due to weak default credentials or other weaknesses.
