Description
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, FreeScout-s linkify() function in app/Misc/Helper.php converts plain-text URLs in email bodies into HTML anchor tags without escaping double-quote characters (-) in the URL. HTMLPurifier (called first via getCleanBody()) preserves literal - characters in text nodes. linkify() then wraps URLs including those - chars inside an unescaped href=-...- attribute, breaking out of the href and injecting arbitrary HTML attributes. Version 1.8.213 fixes the issue.
