CVE-2026-14226 Easy Appointments CVE debrief

Who should care

Site administrators using the Easy Appointments WordPress plugin should be aware of this vulnerability, especially those with subscriber-level users. The vulnerability could allow unauthorized access to booking information, which could be sensitive. Site administrators should review the official advisory and ensure the plugin is updated to version 3.12.28 or later. Additionally, they should consider restricting access to appointment-listing REST endpoints to prevent unauthorized reading of bookings. Security teams responsible for monitoring and incident response should also be aware of this vulnerability and prepare for potential exploitation attempts.

Technical summary

The Easy Appointments WordPress plugin before 3.12.28 does not require a sufficient capability on one of its appointment-listing REST endpoints, allowing users with subscriber-level access to read all bookings on the site. This includes customer names, schedules, and statuses. The vulnerability is restricted to authenticated users with subscriber-level access, which is a relatively low privilege level. The technical impact is that an attacker could potentially access sensitive information about bookings on the site, which could be used to plan further attacks or gain additional insight into the site's operations.

Defensive priority

Authenticated users with subscriber-level access may be able to read all bookings on the site.

Recommended defensive actions

• Verify the Easy Appointments WordPress plugin version and ensure it is updated to 3.12.28 or later.
• Restrict access to appointment-listing REST endpoints to prevent unauthorized reading of bookings.
• Monitor for suspicious activity related to booking data access.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
