CVE-2025-13864: CWE-862 Missing Authorization in cloudways Breeze Cache
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.
AI Analysis
Technical Summary
The Breeze Cache plugin for WordPress versions up to 2.2.21 exposes a REST API endpoint `/wp-json/breeze/v1/clear-all-cache` that is registered with a permission callback that always returns true, effectively disabling authorization. When the API integration feature is enabled by an administrator, this allows unauthenticated attackers to send a POST request to clear all caches (page cache, Varnish, and Cloudflare). This is classified as a CWE-862 Missing Authorization vulnerability. The CVSS 3.1 base score is 5.3 (medium severity) reflecting network attack vector, low complexity, no privileges required, no user interaction, and impact limited to integrity (cache clearing).
Potential Impact
An attacker can clear all site caches without authentication, potentially causing performance degradation or denial of caching benefits. There is no direct confidentiality or availability impact reported. No known exploits in the wild have been documented.
Mitigation Recommendations
A patch is available for this vulnerability. Site administrators should update the Breeze Cache plugin to a fixed version beyond 2.2.21. Until patched, administrators should consider disabling the API integration feature to prevent unauthenticated cache clearing. Verify the vendor advisory for the latest remediation details.
