CVE-2026-11992: CWE-862 Missing Authorization in easyappointments Easy Appointments
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.
AI Analysis
Technical Summary
CVE-2026-11992 describes an authorization bypass vulnerability in the Easy Appointments WordPress plugin. The plugin fails to properly check that a user is authorized to cancel appointments. Although the cancellation action requires a nonce, this nonce is exposed on an admin page accessible to users with the edit_posts capability, which authors possess. Consequently, authenticated users with author-level access or higher can use this nonce to cancel all upcoming appointments site-wide by marking them as abandoned. The vulnerability affects all versions up to and including 3.12.27.
Potential Impact
The vulnerability allows authenticated users with author-level permissions to cancel all upcoming appointments across the site without proper authorization. This results in a loss of appointment data integrity and potential disruption of business operations relying on the plugin. There is no direct confidentiality or availability impact reported, but the integrity of appointment scheduling is compromised.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict author-level user permissions or avoid granting edit_posts capability to untrusted users. Monitor for updates from the Easy Appointments vendor regarding an official fix.
