What is CVE-2025-13864?
CVE-2025-13864 is a medium-severity missing authorization vulnerability in cloudways Breeze Cache, published on 19 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-862
