Technical details

The vulnerability is an HTML/markup injection flaw in the notification handler (notification/handler.py) where scraped page titles are inserted unsanitized into HTML email templates. When a monitored page's title contains malicious markup and the watch_title token is used in notification templates, the attacker-controlled content is rendered as live HTML in the notification message. This affects notification channels including email and Telegram. No authentication is required to exploit this—attackers can inject code by controlling the title of a webpage being monitored. A patch is available in versions later than 0.60.6.
