CVE-2026-63330: Improper authorization vulnerability

Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. Prior to 0.25.6, api_get_recording_stream in warpgate-admin/src/api/recordings_detail.rs protects /@warpgate/admin/api/recordings/{uuid}/stream only with session authentication and omits require_admin_permission for AdminPermission::RecordingsView. Any authenticated regular user who identifies an active recording can subscribe to its WebSocket and receive real-time terminal input and output from proxied SSH, MySQL, or PostgreSQL sessions, including credentials, commands, and other sensitive data belonging to users and administrators. This issue is fixed in version 0.25.6.
