- BLOCKER: stored XSS via inbound sender display name. The reply stub built raw
HTML with the unsanitized From name and set it as innerHTML on the composer's
contentEditable (admin origin) → onerror JS ran on Reply. Now HTML-escape
from_address in the stub AND DOMPurify-sanitize the composer body before
innerHTML (defense in depth).
- Gate the NEW Messages routes with requireFeatureFlag('messaging') per-route
(queue/:id, received/:id, item/*, identities, accounts, accounts/test, send)
— NOT the shared /email mount, so the pre-existing email-config endpoints stay
ungated.
- DocumentActionModal auto-picks a customer only on an EXACT email match
(customer search is prefix/fuzzy), else leaves the picker to the admin.
