Detailsinfo

A vulnerability has been found in Easy Appointments Plugin up to 3.12.26 and classified as critical. Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a authorization vulnerability. The CWE definition for the vulnerability is CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The Easy Appointments WordPress plugin through 3.12.26 does not verify that the appointment targeted by its customer-data update action belongs to the current user; the action only checks a shared nonce that any authenticated user can obtain from their own appointment's edit form. A subscriber-level user with an appointment of their own can therefore reuse that nonce to overwrite the customer metadata (email, name, phone, description) of another user's appointment. Because the Easy Appointments WordPress plugin through 3.12.26 then treats that metadata as the appointment's contact data, a subsequent administrator status change with customer notifications enabled delivers the victim's appointment notification to the attacker-controlled email address.

The advisory is shared at wpscan.com. This vulnerability is known as CVE-2026-14224 since 06/30/2026. The exploitation appears to be easy. The attack can be launched remotely.
