CVE-2025-53840 | Icinga DB Web Exposure of Sensitive Information to an Unauthorized Actor vulnerability

Icinga DB Web provides a graphical interface for Icinga monitoring. Starting in version 1.2.0 and prior to version 1.2.2, users with access to Icinga Dependency Views, are allowed to see hosts and services that they weren't meant to on the dependency map. However, the name of an object will not be revealed nor does this grant access to a host's or service's detail view. Please note that this only affects the restrictions `filter/hosts` and `filter/services`. `filter/objects` is not affected by this and restricts objects as it is supposed to. Version 1.2.2 applies these restrictions properly. As a workaround, one may downgrade to version 1.1.3.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
