WordPress · Mstore Api · CVE-2024-6328
**Name of the Vulnerable Software and Affected Versions**
MStore API – Create Native Android & iOS Apps On The Cloud plugin for WordPress versions up to, and including, 4.14.7
**Description**
The issue is due to insufficient verification on the `phone` parameter of the `firebase sms login` and `firebase sms login v2` functions. This allows unauthenticated attackers to log in as any existing user, 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.
**Recommendations**
For versions up to, and including, 4.14.7, update to a version later than 4.14.7 to resolve the issue. As a temporary workaround, consider disabling the `firebase sms login` and `firebase sms login v2` functions until a patch is available. Restrict access to the `phone` parameter to minimize the risk of exploitation.
