Description :

The remote host runs YaCy, a peer-to-peer distributed web search
engine and caching web proxy.

The remote version of this software is vulnerable to multiple
cross-site scripting due to a lack of sanitization of user-supplied
data.

Successful exploitation of this issue may allow an attacker to use the
remote server to perform an attack against a third-party user.");
