# PROOF OF CONCEPT  
The /coda/frameset endpoint, accessible by any unauthenticated user, reflects the value of the cols parameter.   
Since this value is not properly sanitized and encoded when the web page is rendered, this could allow a malicious actor to execute JavaScript code in the context of another user's browser by only sending to a victim a malicious link.  
  
GET /coda/frameset?cols="><frame%20src="javascript:alert('XSS')"> HTTP/2
