CVE-2026-1310: Migaweb Simple Calendar For Elementor

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
