Cloudways vulnerabilities and threats

Unauthenticated Arbitrary Content Deletion in Breeze <= 2.5.12 versions.

The Breeze plugin for WordPress is vulnerable to Exposure of Sensitive Information to an Unauthorized Actor in all versions up to, and including, 2.5.2 This is due to improper verification of the `wordpress_logged_in_` cookie in the `inc/cache/execute-cache.php` file when the "Cache Logged-in Users" setting is enabled. The plugin parses the username directly from the cookie value (e.g., `username|hash`) using `substr()` to retrieve the corresponding cache file but fails to verify the session's cryptographic signature or validity with WordPress core. This makes it possible for unauthenticated attackers to supply a crafted cookie (e.g., `wordpress_logged_in_fake=admin|fake`) to trick the plugin into serving the cached HTML content generated for an administrator, leading to the disclosure of sensitive information such as private posts (including their full content), the Admin Bar, WordPress nonces, and other data visible only to logged-in administrators or other users.

The Breeze Cache plugin for WordPress contains a critical vulnerability (CVE-2026-3844) that allows unauthenticated attackers to upload arbitrary files due to missing file type validation in the 'fetch_gravatar_from_remote' function. This issue affects all versions up to and including 2.4.4 and can lead to remote code execution if exploited. Exploitation requires the 'Host Files Locally - Gravatars' setting to be enabled, which is disabled by default. The vulnerability has a high CVSS score of 9.8, indicating severe impact on confidentiality, integrity, and availability.

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.
