YOP Poll < 6.1.5 - Authenticated Stored XSS

If you add a new poll, and place a malicious script in the question/answer fields and then press Preview, the script will run. The preview option is available for the editor & administrator role, which makes these roles vulnerable to XSS attacks. 
Proof of Concept
Place a "><script>alert('xss');</script> in the question box and save the post. After saving the post, press preview, and the plugin will show the alert.
