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.","state":0,"publishedAt":"2026-10-28T13:23:13.291+00:00","modifiedAt":"2026-10-28T13:23:13.291+00:00","affected":[{"ecosystem":"Vendor product","name":"xibo-cms","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"xibosignage\",\n                    \"product\": \"xibo-cms\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.4.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","score":7.1,"severity":"HIGH"}],"references":["https://github.com/xibosignage/xibo-cms/security/advisories/GHSA-7j3h-48f7-w4fr","https://github.com/xibosignage/xibo-cms/pull/3492","https://github.com/xibosignage/xibo-cms/commit/96d7b458781b8cd10e64788565fbdeffd15f08cf","https://github.com/xibosignage/xibo-cms/commit/efd13abf868e2386f40929ed6e4f36fead310f20","https://github.com/xibosignage/xibo-cms/releases/tag/4.4.3","https://github.com/xibosignage/xibo-cms/releases/tag/4.5.0-beta"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-52729","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-52729","identifiers":["CVE-2026-52729"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
