Researcher Hunter Jensen (skid)

Description

The Amelia Booking plugin for WordPress is vulnerable to Insecure Direct Object References in versions 8.3 to 9.1.2. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with customer-level permissions or above to change user passwords and potentially take over administrator accounts. The vulnerability is in the pro plugin, which has the same slug.

Wordfence blocked 3 attacks targeting this vulnerability in the past 24 hours.
