Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Glances versions before 4.5.2 have a host validation gap in the REST API, WebUI and token endpoint: they accept any HTTP Host header. An attacker who can get a victim's browser to bind an attacker-controlled domain to the Glances service (DNS rebinding) can read responses from these endpoints, which can include data from a Glances instance meant only for the local network. Upgrade to Glances 4.5.2 or later. Until then, do not expose the service on all interfaces, and restrict access to trusted networks.
