It was discovered that Python Paste did not properly sanitize certain
strings, resulting in cross-site scripting (XSS) vulnerabilities. With
cross-site scripting vulnerabilities, if a user were tricked into viewing
server output during a crafted server request, a remote attacker could
exploit this to modify the contents, or steal confidential data, within
the same domain.
