Hi,

the following vulnerability was published for cacti.

CVE-2017-12066[0]:
| Cross-site scripting (XSS) vulnerability in aggregate_graphs.php in
| Cacti before 1.1.16 allows remote authenticated users to inject
| arbitrary web script or HTML via specially crafted HTTP Referer
| headers, related to the $cancel_url variable. NOTE: this vulnerability
| exists because of an incomplete fix (lack of the htmlspecialchars
| ENT_QUOTES flag) for CVE-2017-11163.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
