In `@app/sagas/init.js`:
- Around line 31-60: The migration in migrateTokenKeysToServerScoped is
incorrectly copying a shared legacy token into every server-scoped slot when
multiple servers reuse the same userId. Update the first pass to detect
ambiguous userId mappings and skip migrating those legacy tokens into new slots,
while still removing the legacy token afterward so affected sessions
re-authenticate safely. Keep the fix localized to migrateTokenKeysToServerScoped
and its use of UserPreferences, TOKEN_KEY_SERVER_SCOPED_MIGRATED, and
getUserTokenKey.
In `@app/sagas/selectServer.ts`:
- Line 174: The server token lookup in selectServerRequest/selectServer should
handle legacy sessions before migration has completed. Update the token read
around UserPreferences.getString(getUserTokenKey(server, userId)) to fall back
to the legacy token key when the server-scoped value is missing, or otherwise
gate the deep-link/share-extension callers until appInit() finishes migration.
Keep the change localized to the token resolution path so direct dispatches
still succeed for legacy users.

Learning: In this Rocket.Chat React Native codebase, the ESLint rule `no-void: error` is enforced. When you see a promise returned from an async call that is not awaited (a “floating promise”), do not silence it with the `void somePromise()` pattern. Instead, handle the promise explicitly by attaching `.catch(...)` (or otherwise awaiting/handling the error) so unhandled-rejection risks are addressed in a way that satisfies the existing ESLint configuration.

File: app/sagas/deepLinking.js:237-243
Timestamp: 2026-05-07T13:19:52.152Z
Learning: In this codebase’s Redux-Saga usage, remember that `yield put(action)` dispatches through the Redux store synchronously, and any saga(s) that synchronously react via action listeners (and synchronous `put` chains) will run to completion before the calling saga resumes at its next `yield`. As a result, within a single saga there is no scheduler interleaving between a `yield select(...)` and a subsequent `yield take(...)` at the next `yield` point, so a check-then-take pattern like `const state = yield select(...); if (state !== TARGET) { yield take(a => a.type === TARGET); }` is safe from TOCTOU races under the synchronous `put`/take model described above.

Timestamp: 2026-06-15T16:17:10.741Z
Learning: When querying the Android SQLCipher WatermelonDB `subscriptions` table, treat the table’s primary-key column `id` as the Rocket.Chat room id (`rid`). In other words, a clause like `WHERE id = ?` should bind `ejson.rid` (this is equivalent to the iOS-side `WHERE rid = ?`). Do not flag this as a column-mismatch issue, because SQLite `subscriptions.id` stores the same value as the Rocket.Chat `rid` field.

Timestamp: 2026-06-25T18:37:25.526Z
Learning: In Rocket.Chat ReactNative tests that mock selectors for `useAppSelector`, don’t require the mocked selector input to be typed as `IApplicationState` when the fixture only includes a partial Redux state slice (e.g., only `server` and `settings`). Requiring the full `IApplicationState` type in that scenario forces unsafe `as IApplicationState` casts and undermines type-safety. For these narrowly scoped selector-mock fixtures, use a less strict type (e.g., `any`) to keep the mock focused on the slice under test.

Security re-review against 5e04c0d
Re-checked every finding from the previous pass against the current head, including the threads that were already resolved. Most of them really are fixed — details below so nothing gets re-litigated.
One resolved thread should be reopened
The native userId-only token fallback is still live on both platforms and the flag that gates it has exactly one writer, in JS. I've replied in the Ejson.java and MMKV.swift threads with the full reasoning, including why the "restore on APP.INIT runs the migration early enough" argument doesn't cover a cold data-only push.
Two items that have no diff hunk to anchor to
- Dead constant.
LoadNotification.java:65still declaresprivate String TOKEN_KEY = "reactnativemeteor_usertoken-";. It is the only occurrence in the file and is never used — the file's actual token access goes throughejson.token()(:96) and thex-auth-tokenheader (:128). Two native declarations of the same key is how the next drift starts; worth deleting while it's cheap. - Scope. The diff is 395 files against
develop— fonts, a UIKit Button, snapshots, CI scripts — plus a Meteor Connect race fix atdeepLinking.js:281-285(thetake(types.METEOR.SUCCESS)wait) and a new 183-lineapp/sagas/__tests__/deepLinking.test.ts. The Meteor Connect fix looks correct, it's just not security. Splitting the unrelated churn out would make the security diff reviewable on its own. Not blocking, and I realise some of this may be unavoidable at this point in the branch's life.
Confirmed fixed — no action
- Consent gate ordering. Now strictly ahead of
getServerInfo(:259),serverInitAdd/NewServer(:271-276) andloginRequest(:287), at both entry points. Declining runs onlyshowToast+fallbackNavigation(), leaving no Server row, no Meteor Connect, no token. It also now sits after the already-connected branch, so a resume link for a Server the User is signed into no longer prompts. - Exported receivers.
ReplyBroadcastandDismissNotificationflipped toexported="false"; the other two were already false. The remaining exported components are MainActivity, ShareActivity, and CallKeep's service behindBIND_TELECOM_CONNECTION_SERVICE. - Key namespace. All the JS call sites route through the
keys.tshelpers now; the only hand-built literals left are native, where sharing a helper isn't possible. - Migration correctness. Every branch drops the legacy slot, the ambiguous-
userIdcase is handled, the orphan sweep is correctly anchored on theuserIdshape, and the flag is only set on success so a throw retries next launch. Tests cover all four branches. - Logging. Every key-revealing
Ejsonlog isBuildConfig.DEBUG-gated and prints key names, not values; the ungated warnings carry no key or token and:214sanitises the URL.
Withdrawing one earlier comment
The RUNNING_E2E_TESTS branch in confirmDeepLinkLogin — @OtavioStasiak was right and I was wrong to push on it. I checked the mechanism properly this time: nothing inlines the variable (babel-preset-expo only rewrites EXPO_PUBLIC_*, and react-native-dotenv only rewrites @env imports), but in a release bundle it's a runtime read against RN's polyfilled process.env, which holds only NODE_ENV — so the gate can never open, and forceLoginPrompt !== 'true' means a deep link parameter can only turn the prompt on. Removing it would also genuinely break the 51 flows that go through login-with-deeplink.yaml, exactly as you said. Not a security issue, and the same idiom is used in 14 other files.
I also withdraw two smaller points from my earlier notes: the orphan sweep is correctly anchored (a Server id always carries a dot, a scheme or a path separator), and the comment-line churn was already your own feedback.

Learning: In this codebase’s Redux-Saga usage, remember that `yield put(action)` dispatches through the Redux store synchronously, and any saga(s) that synchronously react via action listeners (and synchronous `put` chains) will run to completion before the calling saga resumes at its next `yield`. As a result, within a single saga there is no scheduler interleaving between a `yield select(...)` and a subsequent `yield take(...)` at the next `yield` point, so a check-then-take pattern like `const state = yield select(...); if (state !== TARGET) { yield take(a => a.type === TARGET); }` is safe from TOCTOU races under the synchronous `put`/take model described above.

Proposed changes
This PR hardens authentication and deep-link handling against a set of related token-confusion /
silent-authentication issues, and stops exporting Android notification receivers.
The resume token was stored under reactnativemeteor_usertoken-${userId}, with no server component.
Because two servers can legitimately share the same userId — and a malicious server can deliberately
force a collision — that storage slot was ambiguous: the last writer won, and a lookup by a different
server could resolve a token belonging to another server, enabling token confusion / exfiltration.
The token is now keyed by reactnativemeteor_usertoken-${server}-${userId} via a shared
getUserTokenKey(server, userId) helper, used consistently across the login, server-select, and logout
paths, and mirrored on the native side (MMKV.swift on iOS, Ejson.java on Android).
A one-time, two-pass migration in the init saga moves existing tokens from the legacy slot to the new
server-scoped slot (copy every server first, then remove legacy slots, so a userId shared by multiple
servers isn't dropped mid-migration). Logout removes both the new and the legacy slots.
A rocketchat://auth?host=…&token=… deep link could silently authenticate the user into an arbitrary
server, and any app or web page can fire it. Before consuming a resume token for a server the user
isn't already signed in to, the app now asks for explicit confirmation and lands on the login screen if
declined. (Auto-confirmed under RUNNING_E2E_TESTS so the E2E harness, which bootstraps via deep link,
isn't blocked by the native alert.)
The notification receivers in AndroidManifest.xml are no longer exported, closing them off from other
apps on the device.
Notes:
they're added in app/i18n/locales/en.json.

How to test or reproduce
Deep-link login confirmation
"rocketchat://auth?host=your.server.com&token=" (or the equivalent adb shell am
start).
leaves you on the login/outside screen with no session. Before this PR the login happened silently.
Token scoped to (server, userId)
session bleed between servers.
this build over it and relaunch. Expected: you stay logged in (token migrated from the legacy slot to
the server-scoped one), and logging out clears it fully.
Affected screens: deep-link entry (confirmation alert), Servers list / server switching, and the
login/logout flow. No visual changes beyond the new confirmation alert.
