CVE-2026-1310
Simple calendar for Elementor <= 1.6.6 - Missing Authorization to Unauthenticated Arbitrary Calendar Entry Deletion
CVSS Score
5.3
EPSS Score
0.0%
EPSS Percentile
0th
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.
