Background
react-native-reanimated is an npm package that provides a set of high-performance, fully customizable, and declarative animation primitives for React Native applications. It allows developers to create smooth and interactive animations with ease. However, versions prior to 2.10.0 are vulnerable to a Regular Expression Denial of Service (ReDoS) attack. This vulnerability arises from improper usage of regular expressions in the parser of Colors.js, a module within react-native-reanimated.
Vulnerability Detail
The vulnerability in react-native-reanimated can be exploited through malicious input that triggers a ReDoS attack. An attacker can craft a specially crafted input that causes the regular expression parser in Colors.js to enter into an inefficient matching process. This can lead to a significant increase in CPU usage and potentially result in a denial of service condition. The severity of this vulnerability is rated as HIGH with a CVSS score of 7.5.
