Do you have a minimal reproduction please ? At first, it looks like this is due to the revert we made in nuxt 3.12. Nuxt encode the location header when redirecting in SSR

Would you be able to provide a reproduction? 🙏

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritize it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

We have a couple of templates for starting with a minimal reproduction:

👉 https://stackblitz.com/github/nuxt/starter/tree/v3-stackblitz
👉 https://codesandbox.io/s/github/nuxt/starter/v3-codesandbox

A public GitHub repository is also perfect. 👌

Please ensure that the reproduction is as minimal as possible. See more details in our guide.

This example, redirect parameter is Double-Encoded but if i don't use encodeURIComponent, the hash is lost.

I had the same issue. Here is a minimal reproduction.
https://stackblitz.com/edit/github-obvyf4-uwozwd?file=pages%2Findex.vue

path should be /redirected?redirect_to=%2Ftest, but it was /redirected?redirect_to=%252Ftest

Facing same issue. Works fine with 3.11.2 and breaks in 3.12.1 (next release).

From discussion, it seems that this is rather h3 issue. However, I can see that both the versions use exact same h3 version. How is this possible? just curious.

I am also encountering this issue after upgrading from 3.11.2 to 3.12.2. Our authentication server already encodes a query string param for a redirect URI which after 3.12.2 becomes doubly encoded and breaks the redirect parsing.

I suggest this change to be reverted, as this is a breaking change in the 3.12 minor release: https://github.com/nuxt/nuxt/blame/f2868f8c72320009e4502f97456b13f77c6b0322/packages/nuxt/src/app/composables/router.ts#L172

Echoing the impact of this bug:

Redirections to external urls are currently broken, if they include parameters that are already encoded. This is common when dealing with authentication redirects.

Also, this seems like a big blind spot in test coverage.
