CVE-2025-14437 Scanner

WordPress is a widely used content management system that allows users to create and manage websites easily. It is popular amongst bloggers, small businesses, and enterprises for its ease of use and extensibility through plugins. Hummingbird is a performance plugin for WordPress that optimizes site speed, enhances caching, and monitors site performance. This plugin is a tool for web developers and administrators to ensure their WordPress sites run efficiently. The plugin is primarily used by WordPress users looking to improve the performance and speed of their sites. It integrates with other WordPress tools and plugins to provide a comprehensive optimization solution.

The vulnerability detected in the Hummingbird plugin for WordPress allows for the exposure of sensitive information through improper handling in the request function. It affects versions up to 3.18.0 and can be exploited without authentication. This information disclosure can lead to unauthorized access to critical data, such as Cloudflare API credentials. The exposure arises due to insecure log management, where sensitive data is mistakenly logged and accessible. This vulnerability can be exploited remotely, posing a significant security risk.

The technical details of this vulnerability involve the improper handling of log files by the Hummingbird plugin. Unauthenticated attackers can access the sensitive log file located at a specific endpoint: /wp-content/wphb-logs/api-debug.log. This file may contain sensitive credentials, including "X-Auth-Key", "X-Auth-Email", and "Authorization" tokens, due to the plugin's implementation faults. Attackers can send a GET request to the endpoint to extract these credentials. The combination of incorrect status codes and weak validation of content within logs leads to this vulnerability.

When exploited, this vulnerability can have serious ramifications, including unauthorized access to users' Cloudflare accounts, potential leakage of API credentials, and subsequent account compromise. Attackers could leverage exposed credentials to manipulate web traffic, alter configurations, or launch further attacks on affected accounts or infrastructure. The exposure of sensitive data could lead to significant reputational and operational impacts for affected users, possibly resulting in data leaks or service interruptions.
