CVE-2026-30928Public exploitNetwork attack vector

Unauthenticated secret disclosure via unfiltered configuration API

Published Mar 10, 2026 · Updated Mar 10, 2026

Information disclosure in Nicolargo Glances before 4.5.1 allows remote attackers to read configuration secrets through its REST API. The /api/4/config handler serializes self.config.as_dict(), whose nested loops copy every section and option from glances.conf without filtering sensitive keys. When web-server mode is network reachable without a configured password, unauthenticated requests expose backend credentials, API tokens, JWT signing keys, and SSL key passwords.
