From 2.4 until 2.14.9, 2.15.4, and 2.16.2, the /v1/objects API writes attacker-controlled template names into generated configuration without escaping them. An authenticated ApiUser with an objects/create/* permission can inject Icinga 2 DSL configuration, escape the intended object, create additional objects, and exceed the user's assigned privileges. This issue is fixed in versions 2.14.9, 2.15.4, and 2.16.2.","published":"2026-09-18T18:17:09.263","modified":"2026-09-18T18:17:09.263","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/Icinga/icinga2/commit/125b7734e84d03f09b79d36c270152b11629a8c5","label":"Icinga/icinga2@125b773"},"references":[{"type":"WEB","url":"https://github.com/Icinga/icinga2/commit/125b7734e84d03f09b79d36c270152b11629a8c5"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/commit/af4b36e6464b9b214bed270a53d6474cf91eb441"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/commit/eec0d90e8303376fe772b3e4a04e3b064a44cf30"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/commit/faf0450962ad678397991cfdf041810feafa71e7"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/pull/10910"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/releases/tag/v2.14.9"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/releases/tag/v2.15.4"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/releases/tag/v2.16.2"},{"type":"WEB","url":"https://github.com/Icinga/icinga2/security/advisories/GHSA-jgqj-x5j9-vgcm"},{"type":"WEB","url":"https://icinga.com/blog/icinga2-security-release-v2-16-2"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T18:17:09.263"}}
