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.","cvssScore":4.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/lightdash/lightdash/releases/tag/3.137.0","tags":[]},{"url":"https://github.com/lightdash/lightdash/security/advisories/GHSA-h6fw-x63x-9gr6","tags":[]},{"url":"https://www.vulncheck.com/advisories/lightdash-before-cross-project-idor-via-renameservice-dashboard-endpoints","tags":[]}],"exploitRefs":[{"url":"https://github.com/lightdash/lightdash/releases/tag/3.137.0","tags":[]},{"url":"https://github.com/lightdash/lightdash/security/advisories/GHSA-h6fw-x63x-9gr6","tags":[]}],"hasPoc":true,"ai":null}
