From Redwood until Ulmo and Verawood.1, the add_additional_attributes_to_notifications function in openedx\/core\/djangoapps\/notifications\/email\/utils.py assigns notification content without sanitizing discussion-title values produced by get_notification_content in openedx\/core\/djangoapps\/notifications\/base_notification.py. An enrolled student can place CSS-capable markup in the post_title value supplied by lms\/djangoapps\/discussion\/rest_api\/discussions_notifications.py. Digest and batched-email rendering then passes that value through openedx\/core\/djangoapps\/notifications\/templates\/notifications\/digest_content.html as safe HTML, allowing email-open tracking and content spoofing or phishing when another learner opens a CSS-rendering client. The immediate-email path is not affected because it strips title markup and renders a separately sanitized body.
