Attackers can send crafted POST requests to the rename/dashboard endpoint to modify foreign dashboard filters and break charts, or send GET requests to the rename/dashboard/fields endpoint to read field metadata from projects they do not have access to.","epss":{"date":"2026-11-04","percentile":0.07385,"score":0.00178},"exploits":[],"kev":null,"metrics":[{"score":2.3,"severity":"low","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":4.2,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},{"score":2.3,"severity":"low","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":4.2,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793808153019,"publishedAt":1793725568113,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory","technical-description"],"url":"https://github.com/lightdash/lightdash/security/advisories/GHSA-h6fw-x63x-9gr6"},{"source":"CNA: VulnCheck","tags":["patch","issue-tracking"],"url":"https://github.com/lightdash/lightdash/releases/tag/3.137.0"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/lightdash-before-cross-project-idor-via-renameservice-dashboard-endpoints"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/lightdash/lightdash/releases/tag/3.137.0"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/lightdash/lightdash/security/advisories/GHSA-h6fw-x63x-9gr6"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/lightdash-before-cross-project-idor-via-renameservice-dashboard-endpoints"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
