WordPress · Breeze - Wordpress Cache Plugin · CVE-2025-13864
**Name of the Vulnerable Software and Affected Versions**
Breeze - WordPress Cache Plugin versions through 2.2.21
**Description**
The Breeze - WordPress Cache Plugin is affected by an issue allowing unauthorized cache clearing. The REST API endpoint `/wp-json/breeze/v1/clear-all-cache` is registered without proper permission checks (`permission callback => ' return true'`) and authentication is disabled by default when the API is enabled. This allows unauthenticated attackers to clear all site caches (page cache, Varnish, and Cloudflare) by sending a POST request to the API endpoint, provided the administrator has enabled the API integration feature.
**Recommendations**
Versions prior to 2.2.21 should be updated.
