CVE-2025-61907Network attack vector

Restricted data disclosure via unchecked API filters

Published Oct 16, 2025 · Updated Oct 16, 2025

Information disclosure in the Icinga 2 API allows remote authenticated users to read restricted data through object filters. The /v1/objects filter evaluator exposed global variables and object lookup functions without enforcing the API account's variables and objects/query permissions. An authenticated API account with access to a filter-accepting endpoint is required; exposed data includes hidden objects, global values, and TicketSalt.
