Qinglong is a timed task management platform supporting Python3, JavaScript, Shell, and Typescript. 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. This issue is fixed in 2.20.1.
