6.4CVE-2022-4668easy-appointmentseasy_appointments+2
EPSS score
0.47%
The Easy Appointments WordPress plugin before 3.11.2 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.5.3CVE-2026-87966unknowneasy appointments+1
EPSS score
0.30%
The Easy Appointments WordPress plugin before 4.0.2.2 does not perform an ownership or authorization check on its unauthenticated appointment-reservation endpoint before updating an existing appointment identified by a request-supplied id, allowing unauthenticated attackers to overwrite, and through a follow-on cleanup delete, arbitrary appointments.5.3CVE-2026-87965unknowneasy appointments+1
EPSS score
0.27%
The Easy Appointments WordPress plugin before 4.0.2.2 does not use an unguessable token to authorize its mail-link appointment cancellation and confirmation action, deriving the token from a hardcoded source-embedded salt and the appointment's creation timestamp, so unauthenticated attackers who know or guess that timestamp can cancel or confirm arbitrary appointments.4.3CVE-2026-19406unknowneasy appointments+1
EPSS score
0.32%
The Easy Appointments WordPress plugin before 4.0.1 does not restrict one of its appointment-listing REST endpoints to the records belonging to the requesting user, allowing users with contributor-level access to read all bookings on the site, including customer names, schedules, and statuses.4.3CVE-2026-14188unknowneasy appointments+1
EPSS score
0.32%
The Easy Appointments WordPress plugin before 3.12.28 does not perform a per-request capability or nonce check on one of its customer-listing handlers, allowing authenticated users with contributor-level access to read every stored customer's personal information.5.4CVE-2026-14224unknowneasy appointments+1
EPSS score
0.23%
The Easy Appointments WordPress plugin before 3.12.28 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 before 3.12.28 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.2.7CVE-2026-14225unknowneasy appointments
EPSS score
0.32%
The Easy Appointments WordPress plugin before 3.12.28 does not correctly validate shortcode input in one of its block-rendering actions, checking only the first tag of the supplied string against an allowlist while rendering the entire string, allowing users with contributor-level access to execute arbitrary registered shortcodes.4.3CVE-2026-14226unknowneasy appointments+1
EPSS score
0.29%
The Easy Appointments WordPress plugin before 3.12.28 does not require a sufficient capability on one of its appointment-listing REST endpoints, restricting it only to a capability that every authenticated user holds, allowing users with subscriber-level access to read all bookings on the site, including customer names, schedules, and statuses.4.3CVE-2026-14223unknowneasy appointments+1
EPSS score
0.27%

The Easy Appointments WordPress plugin before 3.12.28 does not perform any capability or nonce check in one of its connection-deletion actions, allowing users with contributor-level access to delete the booking configuration and disable the booking system.4.3CVE-2026-14221unknowneasy appointments+1
