CVE-2026-87115
validatedZero produced an exploit or a check.GHSA-x82w-x82x-7998 ↗EUVD-2026-91958 ↗
description
VikAppointments Services Booking Calendar versions through 1.2.21 can allow unauthenticated attackers to delete files on the WordPress server. This may enable further compromise when a File-type custom field is published through a confirmation-page shortcode.
mitigation
Remove or unpublish File-type custom fields from confirmation-page shortcodes and disable the plugin where this is not possible. Restrict public access to affected booking and confirmation pages until a vendor update is available.
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
