Easy Appointments bulk connection deletion lacks authorization
Easy Appointments through 3.12.27 registers the authenticated /wp-admin/admin-ajax.php action ea_delete_multiple_connections but lets the handler read an ids array from the JSON request body and delete the corresponding rows from wp_ea_connections without checking a capability or nonce. Any logged-in attacker with Contributor access can therefore delete arbitrary location-service-worker connection records and disrupt the site's booking configuration.

- Jul 24, 2026
This CVE was published Jul 24, 2026 and is one of 14 known issues for this plugin.
Update, patch or deactivate.
Update Easy Appointments to 3.12.28 or later. The fixed handler requires manage_options, validates the plugin's administrative nonce and connections access rights, converts every supplied ID with absint(), and performs a prepared bulk deletion. Restore deleted connection records from a known-good backup if this action may have been abused.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
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.
