Sunshine Photo Cart WordPress plugin vulnerabilities

The Sunshine Photo Cart WordPress plugin before version 3.7.4 does not check whether a visitor is permitted to access a restricted gallery before accepting comment submissions for its images, while it does perform that check when displaying comments, allowing unauthenticated attackers to inject attacker-chosen content with a chosen author name and email into galleries the owner has restricted (password-protected, email-gated, private, account-only or expired).

The Sunshine Photo Cart WordPress plugin before 3.7 does not validate that a client-supplied price identifier belongs to the item being purchased when it is added to the cart, allowing unauthenticated users to buy items at a lower price defined elsewhere on the site and complete an order at that price, resulting in financial loss for the site owner.

The Sunshine Photo Cart WordPress plugin before 3.6.12 does not perform access control checks in one of its AJAX actions, allowing unauthenticated users to retrieve the comments of images belonging to private, password-protected or otherwise access-restricted galleries.
