What is CVE-2026-63330?

Warpgate, an open source bastion host for SSH, HTTPS, and MySQL, has a vulnerability in its recording stream API. Prior to version 0.25.6, the api_get_recording_stream endpoint was only protected by session authentication without requiring admin permissions for viewing active recordings. This oversight allows any authenticated user to subscribe to WebSocket streams and capture real-time terminal interactions from proxied sessions, which may include sensitive information such as user credentials and commands. The issue has been addressed in the latest release, 0.25.6, enhancing security measures to prevent unauthorized access.

Affected Version(s)
