What an attacker can do

The source says prior to 2.20.1, the init guard middleware in back/loaders/express.ts checks /api/user/init but not /open/user/init, while rewrite('/open/*', '/api/$1') rewrites the whitelisted /open/* path after JWT authentication and the guard have passed; an unauthenticated attacker can send PUT /open/user/init to reset administrator credentials on an initialized instance. Vendor/CNA’s CVSS 4.0 assessment (base score 9.3/10) rates confidentiality and integrity impact as high; availability impact as none.
