Breeze – WordPress Cache Plugin, CVE-2025-13864

CVE, Research URL: CVE-2025-13864
Home page URL: Security reports for Breeze – WordPress Cache Plugin
Application: Breeze – WordPress Cache Plugin
Published on: Feb 19, 2026
Research Description: The Breeze - WordPress Cache Plugin plugin for WordPress is vulnerable to unauthorized cache clearing in all versions up to, and including, 2.2.21. This is due to the REST API endpoint `/wp-json/breeze/v1/clear-all-cache` being registered with `permission_callback => '__return_true'` and authentication being disabled by default when the API is enabled. This makes it possible for unauthenticated attackers to clear all site caches (page cache, Varnish, and Cloudflare) via a simple POST request, granted the administrator has enabled the API integration feature.
Affected versions: max 2.2.22.
Status: vulnerable
