How to Fix CVE-2020-7696

To remediate this vulnerability, upgrade all affected React native fast image dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

react-native-fast-image fixed: 8.3.0 
npm install react-native-fast-image@8.3.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls react-native-fast-image

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-7696, inspect your project dependencies using npm:

npm ls react-native-fast-image

Analyze the terminal output to locate any version of React native fast image in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.3.0), your application is affected.

Note: The npm ls react-native-fast-image command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In React native fast image, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

This affects all versions before version 8.3.0 of package react-native-fast-image. When an image with `source={{uri: "...", headers: { host: "somehost.com", authorization: "..." }}` is loaded, all other subsequent images will use the same headers, this can lead to signing credentials or other session tokens being leaked to other servers.
