CVE-2026-63105

ReadyEcommerce before 4.5.2 contains a stored cross-site scripting (XSS) vulnerability that allows authenticated customers to inject malicious HTML payloads through the chat and support ticket messaging systems by exploiting unsanitized rendering via the v-html directive in Messages.vue, RightChatSidebar.vue, SupportTicketMessages.vue, and SupportTicketDetails.vue.
