Summary

WebSocket endpoint `/api/v2/ws/logs` reachable without authentication even when --auth is enabled

Details

Summary

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).
Gain insight into internal file paths, request/response bodies, and other potentially sensitive data emitted in logs.

PoC

Start Hoverfly with authentication enabled:

./hoverfly -auth

Confirm REST API requires credentials:

curl -i http://localhost:8888/api/v2/hoverfly/version

Connect to the WebSocket endpoint without credentials:

wscat -c ws://localhost:8888/api/v2/ws/logs
# Connected (press CTRL+C to quit)
# … logs stream immediately … (You would need to send a message to start receiving stream)

wscat -c ws://localhost:8888/api/v2/ws/logs
Connected (press CTRL+C to quit)

Impact

Authentication bypass; an attacker receives full application logs, including proxied request/response bodies, tokens, file paths, etc.

CVE-2025-54376 (GCVE-0-2025-54376)

Vulnerability from cvelistv5 – Published: 2025-09-10 19:49 – Updated: 2025-09-10 20:05

Title

Hoverfly's WebSocket endpoint `/api/v2/ws/logs` reachable without authentication even when --auth is enabled.

Summary

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.

Severity

7.8 (High)
