Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Hoverfly is an open source API simulation tool. In versions 1.11.3 and prior, Hoverfly’s admin WebSocket endpoint /api/v2/ws/logs is not protected by the same authentication middleware that guards the REST admin API. Consequently, an unauthenticated remote attacker can stream real-time application logs (information disclosure) and/or gain insight into internal file paths, request/response bodies, and other potentially sensitive data emitted in logs. Version 1.12.0 contains a fix for the issue.
