Name of the Vulnerable Software and Affected Versions: Hoverfly versions 1.11.3 and prior

Description: Hoverfly’s admin WebSocket endpoint /api/v2/ws/logs lacks the authentication middleware present in the REST admin API. This allows an unauthenticated remote attacker to stream real-time application logs, potentially exposing sensitive data such as internal file paths and request/response bodies.

Recommendations: Update to version 1.12.0 or later.
