Recommendation: Plan a near-term fix — a public PoC already exists.

The Taskbuilder WordPress plugin before 5.0.8 does not properly sanitise a URL parameter before echoing it into inline JavaScript on a frontend page containing one of its shortcodes, leading to a Reflected Cross-Site Scripting vulnerability that can be triggered against any logged-in user.
