Stop persisting admin key to localStorage

[potiuk]

Note - this is really just a proposal for the APISIX PMC. this has been found as a small inconsistency during preparation of the securiyt model, and while not a CVE worthy security issue, but more of a "hardening/defense-in-depth" and "consistency" change.

Kind request to consider applying this (or change it in the way that the PMC would like to handle) - or ignore if you do not feel it's worth it - because it does change user experience, so likely also some changelog documentation might be needed if this change is accepted.

Happy to update it if more documentation/migration guides/changelog is needed.

Summary

Stops persisting the Apache APISIX admin key to localStorage
on the dashboard origin. The key is now held in-memory only;
operators re-enter it each browser session.

The current behaviour

src/stores/global.ts defines:

import { atom } from 'jotai';
import { atomWithStorage } from 'jotai/utils';

// Admin key with persistent storage
export const adminKeyAtom = atomWithStorage<string>(
  'settings:adminKey',
  '',
  undefined,
  {
    getOnInit: true,
  }
);

With the 3rd argument left as undefined, jotai's
atomWithStorage defaults to createJSONStorage(() => localStorage)
(jotai docs).
So the admin key is persisted to localStorage under the key
settings:adminKey and re-loaded on init (getOnInit: true).

Why this is too broad

The admin key authorises full Apache APISIX control-plane
mutation — routes, plugins, consumers, SSL certs, every
write operation on the Admin API. The default behaviour widens
the credential's audience to anything that can read the
dashboard origin's localStorage:

• XSS on the dashboard origin — any reflected or stored XSS
  on the dashboard reaches the admin key. The dashboard
  renders user-supplied route names, plugin configs, consumer
  identifiers, etc. — substantial untrusted-text surface.
• Browser extensions — extensions with storage permission
  read localStorage cross-origin under certain configurations.
• Shared workstations — anyone with subsequent session
  access to the same browser profile reads the key.
• Filesystem access — localStorage is stored in plaintext
  in the browser profile directory.

The admin key is a single credential authorising every
mutation against the gateway control plane. Persisting it
broadly is inconsistent with how operators handle other
control-plane credentials (e.g. etcd auth, SSL cert private
keys, RBAC tokens — none of which are stored in browser
storage).

The change

Replace atomWithStorage with atom<string>(''). The
exported adminKeyAtom is still an Atom<string> so
consumers (the existing useAtom(adminKeyAtom) callsites)
are unaffected at the type level. The behavioural difference
is that:

• The key is no longer persisted across page reloads.
• Operators re-enter the key each browser session.
• The settings:adminKey localStorage entry is no longer
  written. (Existing entries are not cleared by this change —
  see "Migration" below.)

Migration

Existing dashboard users will lose the persisted key on first
page load after this lands. They re-enter the key once in the
Settings dialog. The previous behaviour can be restored on a
per-deployment basis via:

• Operator-supplied browser autofill / password manager —
  reduces the persistence to a user-controlled credential
  store rather than the dashboard origin's localStorage.
• Session-replay tooling for operations that genuinely need
  session continuity across reloads.

Neither of those should be the default for an admin-key-class
credential.

The orphaned localStorage entry under settings:adminKey
is harmless after this lands (it's no longer read). A
follow-up could optionally clear it on first load for
hygiene, but that is not required for the security fix and
is out of scope here.

Provenance

The behaviour was identified during a pre-flight security
audit conducted by the ASF Security team at the PMC's request,
documented in the security@apache.org thread on 2026-05-17.
The PMC chair (Ming Wen) chose the "fix in dashboard first"
disposition on 2026-05-18 and on 2026-05-26 confirmed dropping
the dashboard from a separate scan-vendor pipeline pending
this fix.

The direction looks right: replacing atomWithStorage('settings:adminKey', ..., { getOnInit: true }) in src/stores/global.ts with a plain atom<string>('') stops new admin key writes from being persisted through Jotai storage. The current call sites also fit this change: src/config/req.ts only reads the atom to set the Admin API header, and src/components/page/SettingsModal.tsx still updates it through useAtom(adminKeyAtom).

Once CI is successfully executed, we can proceed with merging this PR.

I think I fxed the tests that hanged before - by fixing the harness. Please take a look if that looks good for you :)

[potiuk]

Quick correction to my note above (typo: "fxed" → fixed): the harness fix is in and CI is now fully green — the Frontend e2e suite passes, so the hang/failures from before are resolved. The change is test-only (e2e auth now injects the X-API-KEY header at the network layer instead of relying on localStorage replay); production stays in-memory-only as intended. Ready for your review whenever you have a moment 🙏

Does this mean I have to reconfigure the admin key every time I refresh the page? I'm not sure if this will affect the user experience.

[potiuk]

No - not really, it's the UX change that is explained in the PR description -> it's per browsing session.

As I understand it and worth double checking what happens with this change in - it behaves in this way:

• A page session lasts as long as the browser is open, and survives over page reloads and restores.
• Opening a page in a new tab or window creates a new session with the value of the top-level browsing context, which differs from how session cookies work.
• Opening multiple tabs/windows with the same URL creates sessionStorage for each tab/window.
• Closing a tab/window ends the session and clears objects in sessionStorage.
