Nuxt: Server-side route rules (`redirect`, `headers`, `proxy`, `ssr`) are skipped for case-variant paths when routing is case-insensitive
GitHub lists this reviewed advisory for nuxt, nuxt, @nuxt/nitro-server, @nuxt/nitro-server. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.

source listed>= 4.0.0, < 4.6.2
## Impact With the default `router.options.sensitive: false`, Nuxt's page router resolves routes case-insensitively, so `/Admin` renders the same page as `/admin`. On the server, however, route rules were resolved with Nitro's route-rule matcher, which matches keys case-sensitively. A request whose path differs from a rule key only in letter case therefore rendered the page with none of that rule applied. Earlier fixes (GHSA-mm7m-92g8-7m47, GHSA-hxvh-4h3w-prp9) case-folded the route rules that the Nuxt app itself reads, such as `appMiddleware`. This advisory covers the rules applied on the server: - `redirect`: a rule used to send visitors away from a page, such as `'/admin/**': { redirect: '/login' }`, was skipped, and the page and its server-fetched data were rendered instead. - `headers`: per-route response headers, including security headers such as `Content-Security-Policy` or `X-Frame-Options`, were not sent. - `proxy`: the request was not proxied. - `ssr: false` and `noScripts`: the page was server-rendered, or shipped scripts, de

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
- vendor patch
The original advisory lists fixed boundaries 4.6.2 for nuxt. Confirm the publisher’s latest guidance.

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
