MediumMetricsAV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
Name of the Vulnerable Software and Affected Versions
MStore API versions prior to 4.21.1
Description
The MStore API WordPress plugin fails to verify if the order targeted by its wallet payment handling belongs to the requester. Additionally, it does not deduct the wallet balance for most payment methods. This allows any authenticated user, including those with Subscriber roles, to mark arbitrary orders as paid without any actual payment being processed.
Recommendations
Update MStore API to version 4.21.1 or later.
