Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Glances (PyPI package glances) versions before 4.5.2 are affected. In Central Browser mode, the /api/4/serverslist endpoint can return a server's uri field with embedded HTTP Basic credentials for protected downstream Glances servers, and these credentials are reusable. If the front Browser/API instance was started without a password, which the source describes as common for internal networks, any network user who can reach it can retrieve these credentials once the server has been polled. Upgrade to glances 4.5.2 or later, which is the fixed version listed.
