CVE-2025-53840Network attack vector

Restricted object exposure via unfiltered dependency queries

Published Jul 16, 2025 · Updated Jul 18, 2025

Information disclosure in Icinga DB Web 1.2.0 through 1.2.1 allows remote authenticated users to view restricted hosts and services. Dependency-map queries fail to apply the filter/hosts and filter/services role restrictions, returning unauthorized object nodes without their names. Access to Icinga Dependency Views is required; the exposure reveals topology and status entries but not object names or detail views.
