A user with only the reader role in the root organization (the lowest authenticated role, holding only READ_RESULTS permission ) can issue a single authenticated HTTP GET that can read any files from other orgs - even if they have no explicit permissions in the target org.\n\n\n\nHowever, the problem does not occur in reverse - a user with read access to a sub org is unable to read from other org or the root org.","published":"2026-05-06T14:50:55.631Z","modified":"2026-10-28T02:30:38.701334808Z","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N"},"epss":{"score":0.00236,"percentile":0.14673,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"www.velocidex.com/golang/velociraptor","fixedVersion":"0.76.4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://docs.velociraptor.app/announcements/advisories/cve-2026-6863/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/6xxx/CVE-2026-6863.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6863"},{"type":"PACKAGE","url":"https://github.com/Velocidex/velociraptor"},{"type":"WEB","url":"https://docs.velociraptor.app/announcements/advisories/cve-2026-6863"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:38.701334808Z"}}
