Original description
The description as published by the source.
Stored XSS in the Admin Dashboard via unsafe HTML-stripping (innerHTML) of entity descriptions
Package: @vendure/dashboard (vendure-ecommerce/vendure, latest master) ·
Summary
The dashboard's RichTextDescriptionCell "strips HTML" from an entity's description by assigning it to a live element's innerHTML and reading back textContent. This pattern still executes active markup: a description containing `` runs script when the element is parsed (image resource loads even on a detached node in Chromium/Firefox, firing onerror). Because description is an admin-settable field shown in multiple list views, a lower-privilege administrator can store a payload that executes in a higher-privilege administrator's browser when they open the corresponding list — stored XSS leading to admin-session compromise.
Vulnerable code
packages/dashboard/src/lib/components/shared/table-cell/order-table-cell-components.tsx
export const RichTextDescriptionCell: DataTableCellComponent<{ description: string }> = ({ cell }) => {
const value = cell.getValue();
const textContent = useMemo(() => {
if (!value) return '';
const div = document.createElement('div');
div.innerHTML = value; // line 51 — parses/loads active markup; fires here
return div.textContent ?? ''; // line 52 — reading textContent does NOT undo the side effect
}, [value]);
...
}
innerHTML does not run ``, but it does trigger…
