CVE-2026-61552Network attack vectorHinoki check available

Privilege escalation via unescaped template imports

Published Sep 18, 2026 · Updated Sep 18, 2026

DSL injection in affected Icinga 2 releases before 2.14.9, 2.15.4, or 2.16.2 allows remote authenticated users to exceed API privileges. ConfigWriter::EmitScope places each API-supplied import name between raw double quotes, so an embedded quote terminates the intended import and appends attacker-chosen DSL objects. Exploitation requires an ApiUser with an objects/create/* permission; injected objects can exceed that account's assigned privileges and affect the monitored system.
