Summary
The Gatsby framework prior to versions 4.25.7 and 5.9.1 contains a Local File Inclusion vulnerability in the `__file-code-frame` and `__original-stack-frame` paths, which may lead to file exposure when running the development server.
Risk Assessment
Organizations may be at risk of exposing sensitive files if the development server is unintentionally exposed to interfaces other than localhost.
Recommendation
It is recommended to upgrade to versions 4.25.7 or 5.9.1 to mitigate this vulnerability. Users unable to upgrade should avoid exposing their development server to the internet.
Original NVD description (English source)
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 `[email protected]` and `[email protected]` which mitigates the issue. Users are advised to upgrade. Users unable to upgrade should avoid exposing their development server to the internet.
