jquery.terminal@1.0.2 vulnerabilities

jquery.terminal is a plugin for creating command line interpreters in your applications.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). The code for XSS payload is always visible, but an attacker can use other techniques to hide the code the victim sees. If the application uses the execHash option and executes code from URL, the attacker can use this URL to execute their code. The scope is limited because the javascript attribute used is added to span tag, so no automatic execution like with onerror on images is possible.

Workaround

The user can use formatting that wrap whole user input and it's no op. This workaround will only work when user of the library is not using different formatters (e.g. to highlight code in different way).

$.terminal.new_formatter([/([\s\S]+)/g, '[[;;]$1]']);

Upgrade jquery.terminal to version 2.31.1 or higher.
