"value": "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."
