## FAQ

### What does this mean?

The HTML sanitizer in Roundcube Webmail does not properly handle the animate tag inside an SVG document, which allows cross-site scripting (XSS). This is a flaw where script can end up running in the webmail page.

### Am I affected, and how do I check?

Roundcube Webmail versions before 1.5.12 and versions from 1.6.0 up to 1.6.12 (not including 1.6.12) are affected. The setup involves an SVG document containing an animate tag that is processed by the HTML sanitizer (rcube_washtml). Check the installed Roundcube version number against these ranges.
