{"id":"CVE-2026-52729","published":"2026-10-28T14:17:04.137","lastModified":"2026-10-28T15:24:56.033","description":"Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.3, missing access-control checks on `PUT/DELETE /action/{id}` allow an authenticated user to modify or delete actions on any Layout. Exploitation requires the privilege to allow edits, including deletion, to all created Layouts, which is granted to non-administrators as standard. This issue concerns `Layout actions` rather than the separately reported DataSet export vulnerability. This issue is fixed in version 4.4.3.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/xibosignage/xibo-cms/commit/96d7b458781b8cd10e64788565fbdeffd15f08cf","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/commit/efd13abf868e2386f40929ed6e4f36fead310f20","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/pull/3492","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.4.3","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.5.0-beta","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/security/advisories/GHSA-7j3h-48f7-w4fr","tags":[]}],"exploitRefs":[{"url":"https://github.com/xibosignage/xibo-cms/commit/96d7b458781b8cd10e64788565fbdeffd15f08cf","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/commit/efd13abf868e2386f40929ed6e4f36fead310f20","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/pull/3492","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.4.3","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.5.0-beta","tags":[]},{"url":"https://github.com/xibosignage/xibo-cms/security/advisories/GHSA-7j3h-48f7-w4fr","tags":[]}],"hasPoc":true,"ai":null}
