Authenticated customers can inject malicious HTML payloads through the chat and support ticket messaging systems. This occurs due to unsanitized rendering via the `v-html` directive in the following files: `Messages.vue`, `RightChatSidebar.vue`, `SupportTicketMessages.vue`, and `SupportTicketDetails.vue`. An attacker can submit crafted message content that executes arbitrary JavaScript in the browser of a shop owner or administrator who views the message, potentially leading to session cookie theft and account takeover.
