CVE-2021-24498: Dwbooster Calendar Event Multi View

Medium severity, CVSS 6.1. EPSS: 3.5% chance of exploitation in the next 30 days.

The Calendar Event Multi View WordPress plugin before 1.4.01 does not sanitise or escape the 'start' and 'end' GET parameters before outputting them in the page (via php/edit.php), leading to a reflected Cross-Site Scripting issue.
