Bertrand Delacretaz commented on SLING-2082:
--------------------------------------------

sling/api class modified in revision 1126545 - that class is used by the 
*UserServlets among others, to test it I created a simple test servlet

> XSS vulnerability: HtmlResponse output does not escape URLs in HTML

> A POST request including a <script> in the URL can lead to execution of that 
> script in the browser:
> http://localhost:4502/does/not/exist.html/%22%3e%3cscript%3ealert(29679)%3c/script%3e
> Test with curl:
> curl -X POST 
> "http://localhost:4502/does/not/exist.html/%22%3e%3cscript%3ealert(29679)%3c/script%3e"
> I think this applies to both org/apache/sling/api/servlets/HtmlResponse and 
> org/apache/sling/servlets/post/HtmlResponse, but not sure how to trigger the 
> first one.
