CVE-2026-14854 Details
Description
The WooCommerce Bookings WordPress plugin before 3.11.0 does not limit a user-supplied value before using it to allocate memory in one of its unauthenticated AJAX actions, allowing unauthenticated attackers to exhaust server memory and cause a Denial of Service with a single request.
A denial-of-service vulnerability has been identified in the WooCommerce Bookings WordPress plugin, affecting versions prior to 3.11.0. The issue arises because the plugin does not properly validate user-supplied values before using them to allocate memory in one of its unauthenticated AJAX actions. This lack of validation allows unauthenticated attackers to send a single request that exhausts server memory, leading to a denial-of-service condition.
Users are advised to update the WooCommerce Bookings WordPress plugin to version 3.11.0 or later.
