The Feedback Modal for Website plugin for WordPress is used by site administrators and developers to gather feedback from users directly on their WordPress websites. It provides a customizable feedback form that can be integrated seamlessly into WordPress sites. The feedback data can be exported in various formats for further analysis. This plugin serves small to large enterprises looking to enhance user experience by collecting user feedback efficiently. It adds value by facilitating engagement and continuous improvement through real-time feedback collection.
The detected vulnerability in this plugin involved unauthorized access to feedback data, specifically targeting the "handle_export" function. This vulnerability permitted unauthenticated attackers to exploit the system and export all feedback data. As a result, unauthorized individuals could retrieve sensitive information exported in CSV or JSON format. The lack of a required capability check allowed this exploit to occur, posing a risk to the confidentiality of feedback data.
Technically, this vulnerability arises from insufficient authorization measures in the "handle_export" function. Attackers can trigger the export feature using the "export_data" parameter in the feedback export URL. When processed by the plugin, this request does not validate the user's permissions, allowing any attacker to access exported feedback files. This vulnerability has been identified across all versions up to and including version 1.0.1.
Exploiting this vulnerability could lead to a complete breach of data privacy. Malicious entities could acquire sensitive user feedback, possibly containing private or proprietary information. Such disclosure could result in reputational damage, loss of trust from users, and potential legal consequences for failing to protect user data adequately.
