Exposure of Sensitive Information to an Unauthorized Actor
Sylius is an open source eCommerce platform. Prior to versions 1.9.10, 1.10.11, and 1.11.2, any other user can view the data if browser tab remains unclosed after log out. The issue is fixed in versions 1.9.10, 1.10.11, and 1.11.2. A workaround is available. The application must strictly redirect to login page even browser back button is pressed. Another possibility is to set more strict cache policies for restricted content.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
