CVE-2021-41086

Clipboard-based XSS in jsuites

Description

jsuites is an open source collection of common required javascript web components. In affected versions users are subject to cross site scripting (XSS) attacks via clipboard content. jsuites is vulnerable to DOM based XSS if the user can be tricked into copying _anything_ from a malicious and pasting it into the html editor. This is because a part of the clipboard content is directly written to `innerHTML` allowing for javascript injection and thus XSS. Users are advised to update to version 4.9.11 to resolve.
