MEDIUM Sensitive OAuth Credentials (Nextcloud Client Secret and Apple Private Key) Missing secret: true Flag

In Rocket.Chat, settings are registered with metadata that controls how they are handled by the system. The secret: true option is used to mark highly sensitive settings (such as API keys, passwords, and client secrets) so that the platform can apply special protections, such as redacting them in logs, excluding them from certain API responses, or masking them in diagnostic exports.

An analysis of apps/meteor/server/settings/oauth.ts reveals that while almost all OAuth provider secrets (such as Google, GitHub, Facebook, Twitter, and LinkedIn) are correctly registered with the secret: true option, the following two highly sensitive credentials are missing this flag:

  1. Accounts_OAuth_Apple_secretKey (the private key used for Apple Sign-In authentication)
  2. Accounts_OAuth_Nextcloud_secret (the client secret used for Nextcloud OAuth authentication)

Because these settings lack the secret: true metadata, they are treated as standard non-sensitive settings. This can lead to the exposure of the Nextcloud Client Secret and the Apple Private Key in plain text in logs, diagnostic reports, or settings export APIs, allowing an attacker with access to these outputs to compromise the OAuth integration or impersonate the server to the identity providers.

Steps to Reproduce

Reviewing apps/meteor/server/settings/oauth.ts shows the discrepancy between Nextcloud/Apple and other OAuth providers:

// Drupal (Correct)
await this.add('Accounts_OAuth_Drupal_secret', '', { type: 'string', enableQuery, secret: true });

// Apple (Vulnerable - missing secret: true)
await this.add('Accounts_OAuth_Apple_secretKey', '', { type: 'string', multiline: true });

// Nextcloud (Vulnerable - missing secret: true)
await this.add('Accounts_OAuth_Nextcloud_secret', '', { type: 'string', enableQuery });

Vulnerability: Sensitive OAuth Credentials (Nextcloud Client Secret and Apple Private Key) Missing secret: true Flag

Description:
In Rocket.Chat, settings are registered with metadata that controls how they are handled by the system. The `secret: true` option is used to mark highly sensitive settings (such as API keys, passwords, and client secrets) so that the platform can apply special protections, such as redacting them in logs, excluding them from certain API responses, or masking them in diagnostic exports.

An analysis of `apps/meteor/server/settings/oauth.ts` reveals that while almost all OAuth provider secrets (such as Google, GitHub, Facebook, Twitter, and LinkedIn) are correctly registered with the `secret: true` option, the following two highly sensitive credentials are missing this flag:
1. `Accounts_OAuth_Apple_secretKey` (the private key used for Apple Sign-In authentication)
2. `Accounts_OAuth_Nextcloud_secret` (the client secret used for Nextcloud OAuth authentication)

Because these settings lack the `secret: true` metadata, they are treated as standard non-sensitive settings. This can lead to the exposure of the Nextcloud Client Secret and the Apple Private Key in plain text in logs, diagnostic reports, or settings export APIs, allowing an attacker with access to these outputs to compromise the OAuth integration or impersonate the server to the identity providers.

Proof of Concept:
Reviewing `apps/meteor/server/settings/oauth.ts` shows the discrepancy between Nextcloud/Apple and other OAuth providers:

```typescript
// Drupal (Correct)
await this.add('Accounts_OAuth_Drupal_secret', '', { type: 'string', enableQuery, secret: true });

// Apple (Vulnerable - missing secret: true)
await this.add('Accounts_OAuth_Apple_secretKey', '', { type: 'string', multiline: true });

// Nextcloud (Vulnerable - missing secret: true)
await this.add('Accounts_OAuth_Nextcloud_secret', '', { type: 'string', enableQuery });
```

Affected Code:
- [oauth.ts:43](https://github.com/RocketChat/Rocket.Chat/blob/master/apps/meteor/server/settings/oauth.ts#L43)
```typescript
await this.add('Accounts_OAuth_Apple_secretKey', '', { type: 'string', multiline: true });
```
- [oauth.ts:113](https://github.com/RocketChat/Rocket.Chat/blob/master/apps/meteor/server/settings/oauth.ts#L113)
```typescript
await this.add('Accounts_OAuth_Nextcloud_secret', '', { type: 'string', enableQuery });
```

Acceptance criteria:
- Acceptance is defined by the **actual reported behavior**, not by tests passing.
- Reproduce the issue, or narrow the exact code path that produces it, *before* changing code. State what you confirmed.
- Fix the underlying cause. Mitigations that paper over the reported behavior do not count as a fix.
- Add a regression test that fails on the unpatched code and passes on the fix. If a regression test is genuinely impractical (e.g. race condition, infra-level issue), say so and explain why.
- Existing tests passing is **not** the bar. Do not declare done on tests-pass theatre.

Only change what is necessary to fix this vulnerability. Do not refactor adjacent code or modify unrelated files.

Triage: Reply !fp <reason> (false positive), !valid (confirmed), or !accepted_risk <reason>. Any other reply is saved as a triage note.
Reason is optional but improves future scans — e.g. !fp internal endpoint, not user-facing.
