Prior to 4.4.3, missing access-control checks on `GET /dataset/export/csv/{id}` allow an authenticated user to export data from any dataset, including datasets created by administrators, by iterating over `sequential dataset IDs`. Exploitation requires access to the privilege allowing edits, including deletion, to all created `DataSets` independently of Layouts. This privilege is not granted to non-administrators as standard. This issue is fixed in version 4.4.3.","epss":{"date":"2026-11-02","percentile":0.30719,"score":0.00368},"exploits":[],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793710796849,"publishedAt":1793193910271,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/xibosignage/xibo-cms/security/advisories/GHSA-v6xr-pmg9-qpmv"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/pull/3493"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/commit/98b347d3bf81d369ebe67bde030b913085a11556"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/xibosignage/xibo-cms/commit/bba1bd82da8fb96919ba07462fe06ddacb22116b"},{"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":"d18a85ba1dc769ccdaa793cf1e90d2e9d26f77bdafc5c8e1bb53f0de387d22a6","sources":[{"modifiedAt":1793710796849,"name":"CNA: GitHub_M","retrievedAt":1793711386250,"url":"https://www.cve.org/CVERecord?id=CVE-2026-50541"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793711401637,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-50541"}],"ssvc":{"assessedAt":1793710758757,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Xibo: IDOR (Broken Object-Level Authorization) on GET /dataset/export/csv/{id} Allows Arbitrary Dataset Export","updatedAt":1793711401637}
