Easy Appointments, CVE-2026-11992

CVE, Research URL: CVE-2026-11992
Home page URL: Security reports for Easy Appointments
Application: Easy Appointments
Published on: Jul 10, 2026
Research Description: The Easy Appointments plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.12.27. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to cancel all upcoming appointments site-wide by marking every future appointment stored by the plugin as abandoned. The nonce required to authenticate the cancellation request is printed on the Appointments admin page, which is itself gated only by the edit_posts capability that Authors possess, making the nonce readily accessible to low-privileged users.
Affected versions: max 3.12.28.
Status: vulnerable
