Background
React Native Fast Image is a library that provides a fast, efficient, and customizable way to load images in React Native applications. It allows developers to easily display images from local resources, network URLs, or base64 data. The library is widely used in mobile app development and offers various features for image loading and caching. However, versions before 8.3.0 of react-native-fast-image are vulnerable to a credential leak issue.
Vulnerability Detail
The vulnerability in react-native-fast-image arises when an image is loaded with the source attribute containing a URI and headers. In this scenario, if the headers include sensitive information such as authorization tokens or session credentials, all subsequent images loaded within the application will also use the same headers.
