CVE-2026-19995Public exploitNetwork attack vector

Customer-to-admin stored XSS via RMA messages

Published Aug 17, 2026 · Updated Aug 17, 2026

Stored XSS in RMA messaging in Webkul Bagisto 2.4.4 and earlier allows remote authenticated users to run script in viewed RMA pages. The sendMessage handler accepts the message field as a string, stores it without server-side sanitization, and both storefront and admin RMA views inject the stored value into the DOM with v-html. Reachability requires a customer account that can post to an RMA thread; when an administrator later opens the same request, attacker-supplied JavaScript runs in the admin-facing page context.
