Credential disclosure via key-only config redaction
Published Aug 17, 2026 · Updated Aug 17, 2026
Information disclosure in Nicolargo Glances before 4.5.6 allows remote attackers to read stored credentials via unauthenticated config API requests. In glances/config.py, as_dict_secure() masks values only when an option name matches its sensitive-key regex, so public_username stays visible and public_api URLs with embedded userinfo are returned intact; glances_restful_api.py then exposes that sanitized output through GET /api/4/config and GET /api/4/config/ip when no password is configured. Reachability requires web server mode without --password and an [ip] configuration that sets public_username or embeds credentials in public_api, and the disclosed secrets can be reused against downstream services, but the published record describes no direct write or code-execution path.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
