CVE-2026-23477

Rocket.Chat Unauthorized Access to OAuth App Details

Rocket.Chat is an open-source, secure, fully customizable communications platform. In Rocket.Chat versions up to 6.12.0, the API endpoint GET /api/v1/oauth-apps.get is exposed to any authenticated user, regardless of their role or permissions. This endpoint returns an OAuth application, as long as the user knows its ID, including potentially sensitive fields such as clientid and clientsecret. This vulnerability is fixed in 6.12.0.
