Description
The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 4.15.2. This is due to the use of loose comparison in the 'verify_id_token' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to an @flutter.io email address or phone number. This also requires firebase to be configured on the website and the user to have set up firebase for their account.
