Original description
The description as published by the source.
Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, as_dict_secure() in glances/config.py checks only option names and exposes public_username and credentials embedded in public_api values through unauthenticated GET /api/4/config and GET /api/4/config/ip requests. This issue is fixed in 4.5.6.
