LottieFiles for Gutenberg is a plugin used in WordPress to incorporate Lottie animations into websites seamlessly. It's primarily utilized by web developers and designers who want to enhance their sites with interactive and lightweight animations. The plugin integrates with Gutenberg, WordPress's block editor, providing an intuitive interface for adding animations. Due to its user-friendly functionality, it is a popular choice for marketers and content creators aiming to improve user engagement through rich media. The software is widely used on various WordPress-powered websites due to its effectiveness and ease of integration. Many businesses rely on it to visually enhance their blogs and web pages while maintaining optimal load times.
The discovered vulnerability allows unauthorized access to sensitive settings. It utilizes a REST API endpoint to disclose information, potentially leading to account compromise. This vulnerability is particularly dangerous as it doesn't require authentication to be exploited. By leveraging this flaw, attackers can access LottieFiles account credentials of the site owner. The exposure includes API tokens and email addresses, critical components often used in forgiving authentication systems. Overall, the vulnerability considerably diminishes the presumed security inherent in the plugin's design.
This vulnerability is found at the `/wp-json/lottiefiles/v1/settings/` endpoint. The potential for exploit arises when the "Share LottieFiles account with other WordPress users" option is enabled. Unauthenticated users can trigger the endpoint to retrieve settings that should otherwise require authentication. The endpoint exploits the lack of necessary checks on user permissions before performing operations. When a server responds with a 200 status code and contains the word "is_block_logged_in," it indicates a successful retrieval of sensitive data. This reflects a clear oversight in access control within the plugin's architecture.
Exploitation of this vulnerability could lead to severe security implications. Unauthorized attackers gaining access to API tokens could potentially perform actions or retrieve other restricted information from LottieFiles. Attackers may pose as legitimate users, significantly undermining user privacy and data confidentiality. It could also result in spam or other unauthorized activity sent from the affected APIs. Furthermore, the exposure of email addresses can facilitate phishing attacks, intending to gather further confidential data. Therefore, this vulnerability not only threatens direct LottieFiles account security but also broader data breach risks.
