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.","epss":{"date":"2026-11-02","percentile":0.21828,"score":0.00292},"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","version":"3.1"}],"modifiedAt":1793650700327,"publishedAt":1793193793291,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/xibosignage/xibo-cms/security/advisories/GHSA-7j3h-48f7-w4fr"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/pull/3492"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/commit/96d7b458781b8cd10e64788565fbdeffd15f08cf"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/commit/efd13abf868e2386f40929ed6e4f36fead310f20"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.4.3"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/releases/tag/4.5.0-beta"}],"remediation":[],"revision":"4ba790a342afbab5e247514429c00b108c4916bceca7c6ab86507600b42d10cd","sources":[{"modifiedAt":1793650700327,"name":"CNA: GitHub_M","retrievedAt":1793653806862,"url":"https://www.cve.org/CVERecord?id=CVE-2026-52729"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793653808819,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-52729"}],"ssvc":{"assessedAt":1793650690386,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Xibo: IDOR (Broken Object-Level Authorization) on PUT/DELETE /action/{id} Allows Arbitrary Layout Action Modification and Deletion","updatedAt":1793653808819}
