DescriptionNVD

Gatsby is a free and open source framework based on React. The Gatsby framework prior to versions 4.25.7 and 5.9.1 contain a Local File Inclusion vulnerability in the __file-code-frame and __original-stack-frame paths, exposed when running the Gatsby develop server (gatsby develop). Any file in scope of the development server could potentially be exposed. It should be noted that by default gatsby develop is only accessible via the localhost 127.0.0.1, and one would need to intentionally expose the server to other interfaces to exploit this vulnerability by using server options such as --host 0.0.0.0, -H 0.0.0.0, or the GATSBY_HOST=0.0.0.0 environment variable. A patch has been introduced in gatsby@5.9.1 and gatsby@4.25.7 which mitigates the issue. Users are advised to upgrade. Users unable to upgrade should avoid exposing their development server to the internet.
