Cross-site scripting (XSS) vulnerabilities were found in rainloop, a
web-based email client, which could lead to information disclosure
including passphrase leak.

It was discovered that RainLoop Webmail lacked XSS protection
mechanisms such as xlink:href validation, the X-XSS-Protection
header, and the Content-Security-Policy header.

Simon Scannell discovered that RainLoop's Email Viewer allows XSS
via a crafted text/html email message.
