Summary
The Simple calendar for Elementor plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.6.6. This is due to missing capability checks on the `miga_ajax_editor_cal_delete` function that is hooked to the `miga_editor_cal_delete` AJAX action with both authenticated and unauthenticated access enabled. This makes it possible for unauthenticated attackers to delete arbitrary calendar entries by sending a request with a valid nonce and the calendar entry ID.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
