Vulnerability from github – Published: 2026-07-24 15:33 – Updated: 2026-07-24 15:33

Details

The Easy Appointments plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the ea_delete_multiple_connections AJAX action in all versions up to, and including, 3.12.27. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary connection records from the wp_ea_connections table, disrupting the plugin's core booking functionality.

Severity

8.1 (High)
