How to fix?

Upgrade Debian:9 jquery to version 1.11.3+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jquery package and not the jquery package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.
