Versions of jquery.terminal prior to 1.21.0 are vulnerable to Reflected Cross-Site Scripting. If the application has either of the options anyLinks or invokeMethods set to true, the application may execute arbitrary JavaScript through crafted malicious payloads due to insufficient sanitization.

Recommendation

Upgrade to version 1.21.0 or later
