Breeze Cache <= 2.5.2 - Unauthenticated Exposure of Sensitive Information to an Unauthorized Actor via Crafted Login Cookie

5.3
Exposure of Sensitive Information to an Unauthorized Actor
CVE CVE-2026-2128
CVSS 5.3 (Medium)
Publicly Published May 28, 2026
Last Updated May 29, 2026
Researcher Nguyen Ngoc Duc (duc193)

Description

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.
