Description
changedetection.io through 0.60.6 fails to escape the scraped page title in HTML notifications, allowing arbitrary markup injection. Attackers can place malicious markup in monitored page titles that reaches notification channels like email and Telegram as live content when the watch_title token is used in templates.
