General fix:
To address this issue, the application must never redirect directly to user-supplied URLs without validation. The safest method is to maintain a list/array of allowable internal redirect paths (relative or, if absolutely necessary, specific absolute URLs), check if the supplied redirect_uri matches one of these, and only then proceed with the redirect. If the value is not allowed, either ignore the redirect or route to a default safe location.
Specific fix for the code:
- Create a whitelist array of allowed redirect paths (e.g.,
['/dashboard', '/profile']). If absolute URLs must be supported, they must be checked precisely (e.g., matchwindow.origin). - Before calling
window.location.replace, check if the suppliedredirectUriis an allowed redirect. - Alternatively, permit only “relative” URLs that begin with
/and do not contain an external protocol or double slashes. - Implement the check in the same code block as the redirect logic (within
useEffectinApp). - No new imports are required; use native JS for the check.

The best practice is never to allow unvalidated user input to determine navigation destinations. To fix this, we need to validate the value of redirect_uri before calling window.location.replace. There are two common approaches:
- Whitelist Allowed Destinations: Only allow redirects to a set of safe, known URLs (for example, pages within your own site).
- Enforce Same-origin/Path-only Redirects: Only allow relative paths (not full URLs) or verify that the destination is on the same origin.
For this situation, the safest fix within the given snippet is to restrict redirects to same-origin, relative paths.
- Change line(s) where
redirectUriis read and used, so that we only redirect ifredirectUriis a relative path, not a full absolute URL. - Use a well-known utility to check for this (e.g., with the URL API or regex).
- Insert a check before performing the redirect, and only allow if the value is a relative path (not absolute URLs).
Steps to fix:
- Implement check:
redirectUrimust start with/, and NOT start with//(which is an absolute protocol-relative URL). - Optionally, also disallow any
redirectUristarting with "http", "https:", or "javascript:" to block protocol-based and script-based redirects. - Only call
window.location.replaceif the check passes.
Required additions:
- No external libraries required: we can use simple JS string checks.
- All code changes are within the shown region in app/containers/App/index.js.
