The MStore API plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.18.3. This is due to the updateuserprofile() function in controllers/flutter-user.php processing the 'metadata' JSON parameter without any allowlist, blocklist, or validation of meta keys. The function reads raw JSON from php://input (line 1012), decodes it (line 1013), authenticates the user via cookie validation (line 1015), and then directly iterates over the user-supplied metadata array passing arbitrary keys and values to updateusermeta() (line 1080) with no sanitization or restrictions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary user meta fields on their own accounts, including sensitive fields like wpuserlevel (to escalate to administrator-level legacy checks), plugin-specific authorization flags (e.g., wpufuseractive, aiowpsaccountstatus), and billing/profile fields with unsanitized values (potentially enabling Stored XSS in admin contexts). Note that wpcapabilities cannot be directly exploited this way because it requires a serialized array value, but wpuserlevel (a simple integer) and numerous plugin-specific meta keys are exploitable.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the createblog function in all versions up to, and including, 4.17.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create new posts.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to limited privilege escalation in all versions up to, and including, 4.17.4. This is due to a lack of restriction of role when registering. This makes it possible for unauthenticated attackers to to register with the 'wcfmvendor' role, which is a Store Vendor role in the WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin for WordPress. The vulnerability can only be exploited if the WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin is installed and activated. The vulnerability was partially patched in version 4.17.3.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the profile picture upload functionality in all versions up to, and including, 4.16.4 due to insufficient file type validation. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload HTML files with arbitrary web scripts that will execute whenever a user accesses the file.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to SQL Injection via the 'statustype' parameter in all versions up to, and including, 4.15.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the updateuserprofile() function in all versions up to, and including, 4.15.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files (not including PHP files) on the affected site's server which may make remote code execution possible. This can be paired with a registration endpoint for unauthenticated users to exploit the issue.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to unauthorized user registration in all versions up to, and including, 4.15.3.

This makes it possible for unauthenticated attackers to create user accounts on sites, even when user registration is disabled and plugin functionality is not activated.

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 'verifyidtoken' 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.

The MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 4.14.7. This is due to insufficient verification on the 'phone' parameter of the 'firebasesmslogin' and 'firebasesmsloginv2' functions. 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 the email address or phone number. Additionally, if a new email address is supplied, a new user account is created with the default role, even if registration is disabled.
